I've been playing since 2006 and if ppl would'nt try crazy builds we would be stuck with some very boring charecters...
Good playing in my eyes are those that dont quit parties and have some tolerence to each other (we had that on Euro servers) - in short have fun playing their toons,
As far as i could see - those that break under pressure are the so called "proffesionals" that do anything to max their toons and forget the fun part...., perhaps its also an age thing...
Anyway, i wouldnt want to play with ppl that say their own build is better than mine - its just no fun
