That being said on a threat level I would like to see our talent "Command" get a change that makes Cyclone Slash generate a high amount of threat. To make this fair, it should also have it's focus cost changed to 3 and put a 4 second cool down on it and buff it's damage by at least 100%. Currently this ability is lack luster and most people I talk to don't train it and take it off their bar.
Also get rid of Hilt Strike, we can't use the stun when it matters anyway, just get rid of it and give us Force Pull...we're Jedi too it makes no sense that we don't use this ability. Don't tell it's from a PvP stand point because we have Force Push, they aren't the same thing and it's not like we can do Force Push 30 yards out. All tanks in this game should have a pull/threat mechanic. I have a Shadow at 40 and Vanguard at 33 and trust me you do miss it when you play Guardian.
Also boost both AOE and Single taunt to 8 seconds, 6 is a little ridiculous for any class, even the trooper. This isn't needed, it's more of a quality of life buff that any class would love.
Also I do agree with Guardian Slash having a threat gen attached, that is needed. That covers a ranged threat gen, a melee/AOE threat gen, and a single target melee threat gen. As far as being able to survive, it needs to be in our talent tree not really Soresu, but taking away the loss of focus in Soresu would be nice...
