Ok for the person who tell you not use Aim shot has no ideal that talent give you 3% More Damage on next shot in Rotation i like to use this combo in MM
"Killshot" ( 20% left life ) "Seperant Sting" ( one time apply to target chimera will keep it on! ) "Aim Shot" "Chimera Shot" "More the Armor Pen. better this does damage! "Arcane shot!" "steady shot" ( If you got the 640 armor pen Cap'ed this moves up over arcane shot! )
As for Survival you want use an Aim Shot before a kill shot! big Damage or Steady Shot! Timing is everything remember you want to cap Haste in Survival. Armor Pen. isn't important!
"Killshot" "Explosive Shot" "Black Arrow" "Aim Shot" "Steady Shot" "Serpent Sting" ( Hit from Top Down what ever is up first in that order! )
As for professions i find as SuV your best Profession is Engineer with Hyper Asselartor tinkering! with either JC or LW best 2nd profession. As MM JC and BS is the best! and for Race Troll best SuV and Orc Best MM or BM!
