I have noticed that rarely does the stun from surprise attack actually allow me to stun an enemy longer than 1 second. They usually just break out and are immune for what is it 5 seconds? So it seems that NightBlades are pretty SOL if you planned to be a melee dps in this game as we barely have any CC and mediocre (at best) dps. I don't want to pay to change my skills until I hit Vet 10 so I guess I'm stuck using throwing blade for damage.
This brings me to a larger problem of the Nighblade class as a whole in PVP. It seems that we are in need not just of a buff but perhaps a total redesign. Now I am able to kill some players but that seems to be only when they have exhausted their resources or are just plain not paying any attention. I do have a better time killing sorcerers however they can still blink away, in regards to Dragon Knights well if I am able to get them to low health it seems like they have a spell that increases their health 80%, and Templar just have heals on their bars.
Bottom line Night blades need much much better sustained Melee dps, period. O and before anyone can say it I'm trying my best to lrn2play.
