Ex hardcore player here, now semi-casual due to work commitments. Like others have mentioned, this game is all about reflexes and movement. If you can master frogger, you win this game. There need to be more fights which require coordination and strategy, controlling multiple adds (think Moroes in karazhan, 4 horseman in naxx). To be fair there are a few decent fights in coil but sadly t2 is now a fiasco and the only fun fight left in the game is twin. Hoping that t6-t9 will bring more diversity to the fights.
