Like the stitch up that somehow got the Bridgend outpost club into Super League for the next three seasons, ahead of frankly more deserving candidates.
Or the fairness, or more precisely the lack thereof, of the distinctly flexible rules that allowed them to field a staggering 12 bona fide Australians at the Shay yesterday.
Level playing field? I think not.
But the one thing that you cannot argue with is that their coach John Dixon has fashioned a team that knows how to win the matches that matter.
The Crusaders, even with main man Jace Van Dijk back in harness, play a typically Antipodean brand of rugby league: they defend with structure and commitment, they control possession and, generally, save the flash stuff until they make the opposition 40.
It's a simple recipe, but it has worked all season and it worked again yesterday as Celtic wrapped up a win that saw them leapfrog Halifax into second place in the National League One table.
Matt Calland's side are not quite out of it yet - a victory at Featherstone next Sunday, coupled with a win for table topping Salford in Bridgend the day before - might still be enough to sneak them into the runners up spot.
Whether they finish second or third though, there are some hard lessons they need to learn, and learn fast.
Because while they were never really out of this game - they trailed by just two points at the break and were still a chance at 32-28 when returning captain Sean Penkywicz scored with three minutes remaining - you got the feeling Celtic were always one step ahead.
Fax, who had an intensity about their play that has been absent over the last couple of months, certainly had their moments, and things might have turned out very differently if they had taken the gilt edged chances which fell to Mark Gleeson and Paul Smith respectively at the start of each half.
Calland's part timers also had some terrible luck, with Joe Walsh and Mark Flanagan both unable to return after suffering injuries in the first half and Ben Black finishing the game barely able to walk, let alone run.
But the fact remains that champion teams do not regularly complete their sets of six at 50-odd percent, or display the kind of defensive fragility on their own goalline that let the visitors in on three occasions yesterday.
That might sound like a harsh judgement, but it is a realistic one if Fax want to make the jump from where they are now to where they want to be.
They had started tremendously, driving visiting centre Josh Hannay over the sideline inside his own quarter inside the first minute.
But Danny Heaton's knock on seconds later let the visitors off the hook and set the tone for a frustrating afternoon.
Fax should certainly have scored when James Haley's athleticism gave Black a run at the line, but the half back's sharp pass to the supporting Mark Gleeson - who was excellent throughout - went to ground a couple of metres out.
And when Miles Greenwood spilled a Damien Quinn bomb at the other end, Fax old boy Anthony Blackwood was allowed to score the simplest of tries, stretching out from a play the ball on the next set of tackles for Mark Lennon to convert.
The introduction of Frank Watene gave Fax the punch they were so obviously missing at prop, and there were 19 minutes on the clock when the Kiwi charged on to Black's pass and somehow bludgeoned his way over the whitewash to present Graham Holroyd with the easiest of conversions.
Celtic made it 8-6 with a penalty soon after, only for Holroyd's low, skidding restart to find a way between Blackwood and Quinn and present Fax with an attacking scrum 20 metres out.
But, having made the opportunity, they wasted it, forcing an offload on the first tackle.
Celtic promptly took advantage, hooker Neil Budworth charging over to make it 12-6.
The introduction of Penkywicz had certainly sparked Fax though, and the hooker produced a short kick and chase to score straight from a play the ball, Holroyd adding the goal.
Celtic made sure of a half time lead when Walsh was harshly penalised for ball stealing, Hannay booting the penalty, but Fax were well in contention at 14-12.
They should have been in front in the early minutes of the second period, Smith striding clear but being unable to find the supporting Miles Greenwood.
There were other chances too: Penkywicz almost putting David Wrench in and Shad Royston unable to take Penkywicz's flat pass close to the line.
If Fax weren't capable of being clinical though, Celtic certainly were.
Haley's handling error on the 40 metre line gave them possession, and one penalty later loose forward Terry Martin was touching down on the right.
Martin was over again four minutes later, brilliant handling sending him under the posts for Lennon to kick his side into a 26-12 lead.
This being Halifax, that was never going to be game over, with Black beating a handful of defenders in a sensational, and utterly typical, 50 metre dash for the whitewash.
And when Smith and Greenwood set up Damian Gibson with 10 minutes remaining, Holroyd goaling, it was game on at 26-22.
But a mistake from Richard Varkulis gave Celtic the ball close to half way and that proved fatal, second rower Darren Mapp scoring to give his side a 10-point gap with seven minutes to go.
Penkywicz's eye for an opening and Holroyd's marksmanship got Fax back in the hunt again at 32-28 with 180 seconds remaining, but their chances of a last tilt at glory ended with another fumble from Varkulis.
And guess what? Celtic made them pay, Mapp grabbing a second on the hooter.

STAR MAN
If there was a single failing at the heart of Halifax's failure yesterday, it was their inability to go forward in the middle of the field with any consistency.
There was effort in spades: but collectively Fax's big men didn't have the same impact as Jordan James, Gareth Dean and David Tangata Toa.
The exception to the rule was Frank Watene, who worked his socks off in a single-handed bid to get Fax rolling in attack.
The big Kiwi has been getting better over the last few weeks, and was unstoppable at times yesterday.
Coach Matt Calland must sometimes find himself wishing he had another couple of Franks up his sleeve.
Not far behind Watene was returning captain Sean Penkywicz, who certainly gave the side a different dimension on his return from injury.
Penkywicz scored two opportunist tries, might have set up a couple more, and generally looked too much for the Celtic defence to handle.
Fax's on-field leader hasn't had the best of years because of injury.
But if this performance was anything to go by he could be about to make up for lost time.
The final point goes to Fax's other hooker, Mark Gleeson.
Gleeson was tireless, with and without the ball.
And his combination with Penkywicz - Calland left Gleeson at loose forward in the closing stages - looks highly promising ahead of the play offs.
