Possible bug with Wampa omicron not working in GAC

I pulled data from SWGOH.gg on seasons 34, 36, and 38 (all 5v5) where Wampa was used against a Mon Mothma-led team. These are the results for the 5 most commonly-used teams (slots 4 and 5 change a bit between seasons but there are 3 clear most-used teams). The win rate between the three seasons is mostly consistent, varying only a few percent, except for one case:

When Wampa fights a team of Mon Mothma, Cara Dune, Hoth Rebel Scout, Kyle Katarn, and Pao (by a factor of 3x-4x the most commonly-used defense), Wampa historically won 82%-83% of those battles. But in the first round of season 38, that dropped to 71.4%. No other Mon Mothma team composition saw a drop like that.

I heard several accounts of Wampa performing worse against General Grievous teams so I looked at that. This data is a little trickier to spot any anomalies because Wampa's performance against GG teams on the whole has been declining (unlike against MM teams). However there was one team where Wampa's performance decreased dramatically in round 38, and Droideka appears to be the factor. While the Droideka omicron doesn't affect GAC, we should expect that people who gave DDK the new omicron might also have put extra gear and relics on DDK, and given DDK's ability to unleash a huge amount of damage at once, that may explain why that team performs much better than other GG teams in round 38 so far. Curiously, Wampa's performance against GG teams with IG-88 did not decrease in round 38.

If you are willing to dig deeper, it seems your attention might be most valuable if focused only on the Mon Mothma + Cara + Scout + Kyle + Pao teams to explain why they are suddenly performing much better against Wampa.
