Soo you've decidaded to invalidate GG against JKR?

Well - I was able to get first with GG a week after his release. I still am, cause DRs are a cakewalk. Malak 5* is also beatable with GG. But now JKR is not. So far there are more DRs than JKRs so I'm still able to be first.

But invalidating a squad in that manner is horrendous.
