Enc AoE Mez over-rated?

[SenoraRaton]

I'm a 30 enchanter, and I just can't find a use for AoE Mez, is it bad, or do I just not know how to use it?

The downside is that if I mez myself, I'm worthless for 24 seconds, it hits at most 5 other mobs, and I can just tab cycle targets and mez them one at a time. It is also chaotic because resists, or mez breaking means I WILL die, because now everything wants to agro me.

Does it become necessary at some point? It just feels like it takes up a spell slot, and I never use it, and when I do, I regret it. Tab targeting single mezzing seems much more effective.
