I have been looking over the skill trees that allow certain players to have immunity to stuns when they are performing a certain action. I believe that something like that should be applied to the Sentinel/Marauder because doing all attacks are easily interrupted especially the main skill of master strike where everyone and their dogs wait for that to happen so they can easily maneuver out of it, and I spec so they can't and here they are running away. It's even a 27 sec cd which by all accounts I most likely get one chance to use it during a pvp fight before I die. This is very aggravating especially with bubble specs who seem to stun me every 5 seconds. Really, this is an unfair, very unfair advantage.
