I tend to agree w/ kythik on this one. We need something else for raid mobs. I really love our current evade but since I've hit 60, the more things I raid the more I see our need for something else. With the con changes, raid mobs (particularly 67s) are very very resistant to just about everything. This seems to translate to resisting taunts as well, which is definitely not a good thing for me. In order to get things rolling smoothly, I need to hit dispatch debilitate and murderous rake as close to the beginning of the fight as possible. This allows other classes to land necessary spells, such as stuns, stifles, etc. The problem is that dispatch alone is almost enough to rip agro from even the best tanks. However, it is worth noting that revoke debuffs enough parry that riposte deaths when you turn it arent usually an issue. Nevertheless, I still get one shotted when I am hit, so befuddle adversaries doesnt do me much good. Even if I dont rip agro at the beginning, I'm sure to get agro right away when the tank gets mana tapped to 0. Really I see two possible solutions: either lower the hate generated from our debuffs or give us some other evade similar to what swashies have.
Perhaps they could rework deceit to have a longer duration and have an evade proc attached to it =). Then it might actually be worth buying.
