Viability of Bard Mesmerise Ability

[Videri]

The single-target mez is great. Being able to mez up to 3 or possibly 4 mobs is amazing. You'll save lives.

It won't be very reliable on yellows+, and it will get you killed because it's big aggro.

I recommend not chain-mezzing a mob unless you want aggro. If someone else is supposed to tank, you should mez a mob as little as possible. While playing my warrior, I had this bard just roll mez on one yellow add even though I told him not to re-mez it over and over. I couldn't take it off him despite multiple procs (and Taunt doesn't work on mobs equal to or greater than your level) and he died. My point is, sometimes it's ok not to mez and to just let the tank tank. Meanwhile, you keep rolling that mana song and everything else, and the group does just fine. Enchanters do that too, mezzing too much. Why mez Mob 2 when Mob 1 is at 30% hp? Now the enchanter needs a heal...and a re-Rune...and so on.

If you're fighting by a zone line, you can zone over and back to completely lose aggro on mobs you've mezzed a lot and allow a tank to pick up aggro.
