I dare to disagree in one point, the level
Different builds start to be usefull with different stats, for example: with a 2h char i started scoring kills on lvl 11, with my archer pretty much on the moment i could wear my bow, on the turtle i yet have to kill something on lvl 15(yeah i suck on that), so, it is not needed to get to lvl 30 actually
lvl 22+ seems more reasonable, considering it takes just an afternoon to get there.
But other than that, i agree, people should not bitch about something unless they try to play that also
