I simply think you don’t actually understand how gear works in this game and why it contributes to the problem
This same thing happened in dead ends. Everyone was like “oh my god guys healers are fixed this is so good” when everyone was running around in AF gear for EW, then surprise surprise crafted gear came along and completely neutered the expert dungeons and the rest of EW is history, haedalyn was also praised as the “cure” to healers and damn she was fun week 1, but they just never repeat that
You can already see this happening with the level 91 dungeon, the most dangerous attack (the tornado that sends out star AOE’s) is skipped half the time now and even when it isn’t if you are in synced down AF gear you can survive 3 hits with it on a healer now
2 weeks per expansion of “everyone has no idea what they are doing and is in crap gear” does not make an expansion, if they continue to sync level 100 content as tightly as it is now because of the garbage gear you may have a point but experience shows they won’t
Also on the SGE point SGE is the most boring of the 4 healers so no idea what point you are making there
