I love my rogue,but is it just me or is the 3.0 click worthless? I mean to use daggerfall you must stop attacking,hide,sneak then hope next backstab lands. This is great for an opening but during a fight its kinda a pain. My crits are almost as big as what daggerfall does.
To use daggerfall you do have to stop attacking and hide. I can't remember if sneaking is actually necessary but I believe it's not. If you miss something with daggerfall on its most likely a range issue.
Anyway, the 3.0 click is awesome because it gives you daggerfall without having to do those things and the fact that the cooldown on the weapon is much shorter than the daggerfall ability. Further the cooldowns on the weapon and the ability are seperate so you can use one then the other.
The actual downfalls of the rogue classes's dps are the low non backstab damage, the actual base backstab damage of the weapon and the high interaction to dps ratio as compared to rangers.
