Really, have you forgotten while Zaul was necessary in the first place? Let me remind you, the Rogue One movie came out and to try to sale as many characters from the movie (almost all lightside for some reason) devs decided to cram almost all the abilities in the game in just 2 toons. Lo and behold the Chaze meta appeared, to complete and not replace the Wiggs meta that was in full effect since August '16. After some months when the time finally came to shift the meta from rebels, Krennic and DT were release. But surprise, surprise they failed miserably, even though their kit would have been very good, close to OP, if they would have been released before Chaze.
So now, after the devs painted themselves into a corner, they only had 2 choices: either the sensible one to tweak the rebels, but that would have made the people in the title mad, or to release/ rework something even more OP than rebels, which invariably made the people in the title mad.
Anyway after this little recent history lesson, let me ask you, how can you possible complain about the necessary evil while being fine with the root cause that made it necessary in the first place? Chaze aren't OP, just versatile, because of Boba and B2? Horse manure, B2 and Boba
were just enough to seem they were a challenge but not good enough to actually threaten Rebel users, just like you like it, that was why you were dominating leader boards wasn't it? Heck even with Zaul lead added to this counters Chaze is still plenty represented in the leader boards. Zaul is killing every other team outside Rex triple cleanse (which actually include your faves) ? Guess what, that is exactly what rebels were doing since Wiggs. Over 100 toons made irrelevant and unplayable in arenas by 2 OP pairs of rebels. That is exactly what Wiggs is still doing on lower levels now, after a year.
