graphics are cool, animations awesome, music is great, story is infantile and the gameplay is repetetive.
sounds exactly like an updated version of diablo 2, eh? 
I bought it some while ago but couldn't warm up to it. Maybe this kind of gameplay had it's peak during the Diablo 2 days, back when it was new.
Besides, the skill system does it's very best to prevent the abuse of spamming powerful spells ... and finding a way to abuse aspects of the game to pown all and everything was always my top priority in Diablo 2. 
I think I was one of the first people to use the Amazon's Lightning strike skill to devastating effect - even before magic javelins were introduced. Blizzard had to rework the lightning art because then a full specced LS amazon could - with certain items and skills - fill the whole screen with lightning white, slowing the game to a halt and often dropping other players from the game.
