Does the increased damage from single saber mastery off set the extra damage that sentinels get from having a second saber? A better question might be how much extra damage does the second saber provide vs the 20% bonus from single saber mastery?

That makes sense, but what about compared to the other sentinel specs? Is this just a pvp spec or is it viable for endgame PVE?

The "new" concentration spec seems to my untrained eye as very viable with the addition of the two new single target skills, but most of the conversations here are regarding combat and watchman. What is it about this discipline that makes it less appealing?

Do the armor penetration effects of sundering throw and sundering assault stack? I assume it's one or the other.

What should I go with? Have jugg/sent/assassin/sage. Sniper and vanguard are in their 30's. With the time I have left I could top off those two or start a new one. If my main is my sent, are there advantages to leveling up smuggler or trooper as opposed to the imp classes?

Makes sense. Thanks all.

I know it is not a dps tree, but I also know respectable dps can be had here. What rotations are you using to maximize dps as Darkness/Kinetic?
