i think d3 is great bcz it is more versatile...u are not stuck with skill tree..plus if u played wow b4, u will notice that there will be a dominant skill build for each class...and people tend to use same skill build for each class...kinda boring.........
with d3 u can used diff skill build, no right or wrong..go with skill that suit ur gaming style...plus u need to match ur skill with suitable items..
for me no prob for d3 and great job by blizzard (except for crappy server)
