I do think that it is false to put the base crit down on 2 instead of 5% I think as a "noob" player Crits, especialy motivate you to game on. And you should get them often enough.
I think it is good to get the overall critchance down to 12 percent from 20% but 8% Crit chance für skilled players should be enough... Instead of 10 they now have...
