I'm new to wow, and I'm playing the hunter class, currently 501ilvl pvp, as MM i pull 100k(still low i think) dps but in BM it doesnt go more than 60-70k tops, i have hit and expertised cap as well with the grevious bow too , and i think i'm following guides as well, I dont know what I'm doing wrong
PLZ HELP!!!!

get more PvE gear obviously, if your MM reforge everything to crit , use wolf for 5% more crit, or maybe your shot rotation is just bad
