Just a little to buggy and lazy.
Biggest flaw:
Catti can literally walk through any Dungeon on any difficulty with time. The enemies never aggro her. Also, her basic animations are ridiculous. They put a lot of focus on her abilities looking sweet. All except the Ult.
Pros: epic maps, fluid fighting (except Catti), enemies are visually awesome, atmosphere is well within the lore and I am enjoying the story!
