Ok, I find this thread a very interesting read.
So..

Here I go.. I think the game should have a toggle option for AA.
If you have AA on, you remove any chance of scoring Criticals on Mobs.
With AA off.. Can can get Critials. This will reward players who chose the more manual route.

I Personally have problems with my hands, and I would think about playing this game more if I didnt have to spam a key every 2 to 3 seconds. ATM I can only play in small periods due to this.

So is someone wants to go out and solo farm, swtich AA on, you can chat on the LS while fighting.
Want to party and be all serious, switch AA off and kick some butt.
