I stayed all the way.
Not gonna lie, it was harder as a result. But I managed to clear all of the mythic content in CN did got Glad this season in 3v3 and 2300 in RBG/2v2
Only thing I am trying to to achieve still is to get into 15 Mythic+ Groups.
Overall, I managed to overcome the 'best spec' dilemma and I stayed with bad spec for once. Guess what? I managed to get everything done, regardless of simscrafting and all that garbage, it even changed my mindset to lean towards playing a spec that feels/looks fun rather than which one does highest dmg.
