Went ahead and did a few world quests, put all that AP into the weapon, got that massive power spike.
Sure is nice to know it's all going away in a few months, all those cooldown lengths, all those conveniences. Getting weaker is really good RPG design!
The few things we keep, we have to pay for with our our talent points, of which we haven't gotten more in 4 years, and even then it's almost always a severely nerfed version.
Seriously, I am really looking forward to the game content in Battle for Azeroth but what they're doing with class design is pure fucking shit. I've never really complained that much, changes happen, nerfs happen, but god damn this is going to suck.
