I just thought I would give a suggestion to the Invisible Man Discipline that Rogues get at 70.
I was thinking that in addition to the hate decrease it could give a fairly large avoidance boost. This will help with rampage and would be hard pressed to exploit to let rogues actually tank anything considering the Hate Decrease component already attached.
I feel like being mostly invisible would make me reasonably harder to hit, even if you could see my weapons.
As it stands now I very rarely use this disc, and considering its our "upgradable through drops" disc, It really should be more useful.
