Mez overrides
 

I was wondering if not being to cast single target mez on a mob that was either AE mezzed or Bard mezzed was working as intended? The message was "that spell did not take hold".

Any idea on if/when this can be fixed?

That is classically how they worked. Detriment of using AE mez.

AE mez was always the Oshit button to just delay a wipe.

Yea that is a bit wierd. You can AE mez mobs, then you can't Dazzle(49mez) or Entrance(34/39?mez). However, you can Entrance(16mez, 46sec) a AE mezzed mob - and then you can Dazzle or Entrance it afterwards.

AE mez + stuns + single target saves the day!
