CHA's effect on chanter mezz?

[TheFishyOne]

'ey guys.

I just rolled a Gnome Chanter and, knowing starting stats don't mean much in the endgame, I gave him 25 points into INT, and 5 into CHA; I figured that having an easier time leveling was more important than RPing a charismatic Gnome. =) Anyhow, I know CHA affects a chanter's ability to charm and mezz, but on live I started grouping fairly early, and contributed to the group by mezzing the hell outta big pulls. I was just curious if anyone had some numbers or theorycraft on how a high CHA affects a chanter's chance to successfully mezz. I don't plan to reroll my Gnome or anything, I just want to know if it's worth stacking large amounts of CHA on gear once I get to a respectable level.

Many thanks in advance!
