meh, im a lvl 69 bower.
today i killed a lvl 76 nuker and a lvl 81 nuker.
nukers of my level get 1 hit crit enough, i basicly 1 hit crit most ppl under lvl ... 73-74, thats nukers when they dont have snow on.
and they dont 2 hit kill me either, no way lolz.
imo bowers and sword shield nukers are the strongest ...
glaviers have really never been a problem for me either, a lvl 69 full sos glavier, with a sos+5 glavie is around equal to me, he has gap 1 i have gap 0, only i aint got no full sos set
as a bower you just need to use your range, after you get stunned or w/e, phantom out and use your range, if your first hit crits go on and most ppl will die lol.
just my experience...
