That shows they’re trying, but if you look at the top 20 keys pushed on Raider IO, it’s still the same god comp for 19 of 20 (and rank #19 is the god comp just with an evoker healer); the damage was done for M+ title seekers.
They clearly are being too timid with their nerfs or simply don’t have a good predictive model for their input tuning changes to arrive at a desired output, so they end up doing trial and error (mostly lots of error as more Guardian Druid/Holy Pally/Fire Mage nerfs are coming on 22-Aug). This sort of tuning also risks the nerfed specs being under-powered if they are not with an augment evoker.
There’s also a nerf to M+ dungeon scaling over +20, but again those that spammed the god comp before any nerfs locked away any contention for title. An effort for show only, as this is likely to be ineffective at offering a chance for title to other comps through the remainder of S2.
