[Suggestion] Accuracy focused new class

A suggestion of a unique playstyle focusing around accuracy,
influenced (or copied..?!) from Mechromancer of Borderlands2

Its primary skills will be focusing around building counters on successful hits
Whereas the counters will alter attack power but decrease the character's accuracy

So, in building the character, accuracy will mainly be focused to increase attack power benefited from having more counters.

Next tier of skills will be using the counters as cost, or activation requirement
Boss fight skills should appear in this tier.

I dont have much idea because its just an idea popped up during I'm gathering..
Discuss :)

I think it is an interesting concept but it would not really work on any Boss fight. In order to counter, you need the target to be attacking you; in other words, it would have to be a tank class. An Accuracy based tank class just wouldn't work. I think it would be interesting to add as an alternate gear setup for DPS classes that solo, but as an overall class it would be flawed in concept.

By "counter" I mean a stack of buff added whenever a condition is fulfilled (in this class, hitting target)
Not the counter with the meaning of "strike back".
