that is how my talents are spread and i'm wondering if this would work well for arenas

ok combat/asasination isnt the spec i would choose (id go 19/0/42). but this spec is fine, only thing take 1 point out of combat and put it into imp eviscerate as well as the 2 points from murder.  blade twisting=complete failure and switch the 2 points from endurance to imp sprint which helps a lot in bgs and arenas. also u should consider dual weilding maces and get mace spec. get a chance to stun and + crit%

i changed my spec recently it was more of a hyprid cb evi/hemo spec before but i changed it again, so i'm 19/0/42 i believe

Hmmm i would disagree combat assination does work because of shiv u get off hand bonus from combat ill link my talents im 41/20/0

in combat get improved sinister, imprvoed slice and dice, lighting reflexes and percision and duel weild spec.

i agree combat can work with assination i tried his spec it worked
