My problem with backstab is that crit damage is capped to the dagger you use, and worse, if you ever actually miss, the enemy will turn around!
My rogue has 5 in one handed, and 50% boost barely gets you 90 damage per 2 hits. level 15 enemies. Maybe I am simply under-equipped, but I find backstab actually USELESS. I switched to bow and do about 3 times more damage, and over 15m and to groups instead of "behind an single enemy"
