Deadknight i dont think you understand how numbers work. You start with 0% crit, you would need to amass gear and points into wit which would take away from the finesse dump that rogues do now since you get 100% crit rate on back stab. Starting off lvl 1 and having 100% crit rate on your attacks is stupid. Which would be the trade off lower damage for higher crit. IF you crit you do the 150% bonus, So no you wouldn't do more damage. Daggers i've seen go as high as 186% (probably go even higher) more damage from crit, they also duel wield which means they are doing 372% damage per back stab. Explain to me how you think this is the same.
