Maybe Role Actions wasn't a good idea in absolute... At least for all actions.
I mean, look at Rampart, for the example.
It's basically the same thing that Shadowskin and Foresight. So... Why did they have removed those two just for Rampart? Rampart, that uses the PLD's animation, since the DRK's one for Shadowskin was really beautiful.
And some abilities like Provoke, Shirk... They should be include in all tanks's set without compensation, since it's basically the goal of the tank: manipulate aggro.
I don't understand the point of Role Actions. They are just actions that should already be in all tanks's set...
