Teeming just got stealth nerfed. Missing mobs in every dungeon compared to how many there were a couple days ago.
Kind of sad Blizzard removes any type of challenge the moment people start complaining about it. I thought teeming was fine, it just forced your group to be smarter about trash pulls and not brainlessly aoe packs down.
I think balance in general is worse than it is in legion, though despite that if you look at the legendary situation in early Legion + the difference that AP made then I don't think the balance in M+ is worse. Legendaries made such a big difference in Legion, at the early stage of the expansion it was literally make or break for a lot of players because large differences in performance were dictated not just by spec but by legendaries themselves, where as now it's just based on spec balance.
Spec balance was better in Legion, but the situation early on was not better on the whole because of Legendaries. The numbers of the dungeon may be off, but that's the same for everyone where as class/spec balance is a different matter.
