Paladins are in a good place when it comes to PvP as far as I am concerned but I can understand how other classes may feel a bit more like a Support DPS. I think Provoke simply forcing a single target to attack/move toward you for 2-3 seconds and perhaps an AoE taunt with Flash or maybe Unleash's range added to the arsenal would help add more utility to their class. I strongly disagree that Tanks should force everyone to attack them non-stop for ridiculous lengths of time, but I think a few seconds at a time - both single target and AoE - would help balance the board a bit so that every tank has the ability to better protect their allies in a more direct sense.
