im a blader so i will be biased towards them, go blade only if u want to have fun and look cool, glavies can kill but can also be killed easy, i havea blader and despite wat ppl say i dont find it THAT hard to kill, just takes a little time, but jeseus if iu want to lvl fast go glavie
edit also:
wen the 90 caps comes out we can only guess which build will have more pwning power, so just go w/ what u like
