Deadeye LV 75 - struggle after finish Quest / -> no chance to kill Crimson Monsters in Maps

Finished Act 10 recently - Kitava was not a problem for my Deadeye Ranger LV68. Now Im LV 75 and I'm struggling.

Maps drive me nuts, expecially the Ore encounters. Same with hastes.
Worst: No way to kill the crimson ore gang even in 5 tries. Getting the ore in time is impossible for all ore encounters.

Any idea?

I know, my RESISTANCES are not balanced, BURNING ARROW + TOXIC RAIN are not the best choices. My 6 SHRAPNEL BALLISTAS with 1150 DPS are probably ok.
