I'm a bit against in losing flash, without Flash it makes me feel less efficient as a tank.
Usually one flash was all I needed to do pull one group to another. Like if I'm going to do large pulls, I can't do Total Eclipse once, one of them will lose aggro on the way and attack other party member as well. So can't do it without Prominence which makes it a bit troublesome.
Sure it's good that enmity actions are also dealing damage, but I don't find it easier..
