I've played as a troll in a group and i felt so out of place that i now prefer not to group unless it's for an unachieveable quest (poison quest at lvl 20). I love to start off with a backstab after i pickpocket then sinister strike, gouge, sinister strike, kick and then wait for my health and stamina to regen, then evisecrate, by then it's down to 20-10% health left, which i finish off with regular melee
