The new pvp have good idea and less good idea.
The consolided combo don't bug me too much, its not hard to do 1,1,1,1 thats true, but its not hard to do 1,2,3,4 also, everyone can count 1,2,3,4 i think, it's can be boring to press the same button, but it save space on hotbar also, so its not the worst idea i think, i was not missing a combo before because i was doing 1,3,2,4... it change nothing, exept i have to use the same button now.
But why reducing so much the toolkit, and why 12 button when even gamepad player can afford to 16 buttons to be able to play with a single bar.
It feel to much reduced to the maximum.
