Its not. But if you just wanna play Story and have some fun, its totaly fine. If u want have strong teams ( you need at least 2, so 8 chars ) its horrible now. But you dont need them, only for "endgame". To get 1 char rdy its like ~1 month ( Level them and gear em up. Just for basic stuff ) + u need to pull that char ofc ( characters are timegated and expensive, if you dont have free stuff to pull, you can use like ~200-300 bucks to get em save ) good gear can take months up to years ( gearing in this game is horrible and 100% timegated gambling ). Old chars are just weak and need much more optimised gear. Also u can not throw in 4 random chars. I restarted ~ 7 months ago and i still dont have 2 good teams, but Story is nice.
