I feel like it's been enough for me, probably cause i haven't blasted through it like most people, there are some very tedious quests that take grind to another level, but with a friend, or by yourself with music, they're still fun. To me it's been pretty good, the rewards are, better, but will still kinda piss you off, but then again stuff drops like candy now. I really like TTK, but it's up to you, if you get it, i advise not worrying about getting all your characters up, and make sure to play other games, so you don't get bored with the grind. Good luck dude.
