The long, well written, perfectly elaborated post by John Salera is very nice, kudos, but I can't get around the fact that they seem to have been too late adapting. Again.
I mean, "the speed meta was getting out of hand". What speed meta? Everyone and their dog are playing Dooku dodge because his leadership has clearly been overcompensated with the last update.
A lot of things about this update are good and indeed add longevity to the game, but longevity doesn't mean every single battle has to be a tedious, endless chore. Basically, just removing protection from the Challenges and reverting the AI opponents to before wouldn't be too much of a drama, wouldn't it? Because now I spend 10 minutes wasting through the endless mobs of level 1 and 2 before finally wiping the boss within the minute. That ain't balanced.
