Shield Bash GCD Removal

[Brannigan]

If there was a better in-game threat meter which would show my threat value relative to every other party member (similar to KTM), then I could understand asking the player to decide between attacking or waiting for an upcoming attack.

Look at your party list (not the encounter list) when you have a monster targeted and are fighting it. The bars show enmity relative to #1.

Also I prefer Shield Bash as-is. The benefit of being able to do it so often outweighs the penalty of having it on the GCD in my opinion. Tank enmity is so far beyond everyone else that you can kind of just stop attacking if you need to after a certain point.
