Classic Help with low BM damage

Hi!So i can't help feeling like i don't do any damage, im sitting at 398 ilvl and all 4 pieces bonus, i don't have the Rasz bow.I open with BS, BS, BW, BS, and then i try to maintain full uptime on both frenzy and beastcleave while spamming as much KC as possible.People often pop off 100-250k dps on some big pulls where im kinda stuck at the 70-90k dmg at the same pull but thats probably normal since i don't have any real burst.I tried swapping to MM and gained around 10k+ dps average on the first 3 dungeons, and i dont have too much experience with that spec so i can probably optimize that but i would just prefer to play BMBeneath i have linked 2 pictures of a +15 AA i just did if that gives any kind of usefull info, the rogue in the dung was 411 ilvl, i doubt that increase would almost double my damage.https://ift.tt/okIKD8N https://ift.tt/p91LMNQ via /r/wow https://ift.tt/LAqKIaB
