looks like you havnt played the game for real. go to diabloii pvp forums and ask them how much the scene has changed every time a major patch came out. there are so many extereme builds for palys alone, all having pros and cons. a serious barb not using use ww as primary attack i am yet to hear of, but there are so many differnt variations you could give to a barb, i have 1 mf barb, 1 all vit s/s tweaker, 1 itd tank, 1 s/s tank. my suggestion is you do more homework before you write off a game thats been quite prosperous. you might be a 'experienced' pvm player, but if you say most necros use BG/IM you would be laughed by everyone 'in da know'.
just to give you an idea, here is a typical well-balanced all purpose necro
