Ahh so it is 28%, I was looking at this
site for that info since I aint in-game. That's a hell of alot better than 16% and will come down to what RoK has. As far as Raiding, I've been everywhere except MMIS and EH. My experience is that I have little to do with adds, I go after the big guy and if adds pop the MA taunts them off and I keep hitting the big guy. My point is assassins can't deal with group encounters as well as many other classes, but few classes can deal single-target damage as well as an assassin can. So in my situation my biggest issue is survival since I don't have all top-end gear and before anyone acquires the RoK gear, I believe it may be the same to come.
As far as Freezing Strike while soloing, yeah it is definitely helpful but right now I'm soloing the first part of Acad trying to get that friggin Earring (which refuses to drop). Anyway I still don't see root lasting 12 seconds. MM helps alot though since it helps it trigger off early and more often. Frontload is by far the bigger impact in soloing with the right gear in my situation.
I'm not disagreeing that your's and Vaanir's setup isn't going to be the best (I agree) but it also goes by what gear you have and overall tactics to make it the best. Right now I aint in a guild with 24 constant players so most my Raiding is with Pick-up raids, nor do I have the best gear to always survive raids. Which is why I am trying to increase my Health over alittle more DPS. Once I get some top-end gear I will most likely respect into Surrounding Attacks since I will no longer need such an emphasis on survival.
BTW where does Robe of Battle drop??
