Our mez song ig useful till at least lvl 30. I say this because in my
cleric's group (which is now lvl 30) our bard still uses lullaby effectivly.
I'm not sure when it becomes useless (Elfson just about never used it
because high taunt factor in pickup groups was too risky for him), but it
has some use at least. Pixie Strike on the other hand is pretty weak for
mezzing. Though I still love the song for its stun effect. My guild (who I
now spend most of my time grouped with) was shocked when a healer mob bot
off a heal in combat. "Elf, what did you fall asleep there?" (I actually
didn't knwo the mob was a healer thus wasn't stunning).

But that shows how useful that song is, my guild just assumes that every
heal is going to get interupted. (Obviously not just me doing it). SO that
song is still useful.

Face the facts, we knew a month ago we would never get to mez at higher
levels. Live with it. I don't know why you masochistly read Gordon's
posts anymore. You know what he's going to say.
