Well cha is supposed to have an effect on mez, memblur and lull spells for chanters but the level of effectiveness is limited at best.

From experience, when I'm in the planes for example (but same could be said for Solb or wherever), when I have to mez a yellow con (or high magic resist mob) usually the mez will be resited unless I tash first. Even after tash, some mobs will resist the mez up to 2-3 times before the mez will land.

During this time you get beat on and you get beat on hard. You will want to have at least 2 (or 3) stuns loaded just to be able to land the mez without getting interrupted (I strongly suggest our quick aoe stun followed by the whirl line for the nice increased duration).

Now everything I just mentioned happens regardless of whether or not I'm wearing my charisma gear (which adds like +60 charisma for me currently, putting me in the 220-230's).

So long story short, if +60 charisma is not helping me out with general every day CC then adding 20 charisma at character creation is a waste of starting points.
