Chanter top slot discussion: swap or CC?!

[Tecmos Deception]

Mostly because I didn't know top slot refreshed differently from clickies than the other slots until after I'd already been playing a chanter on p99 for multiple years, an ... lol, just finished camping out even though charm broke while I was typing because my pet didn't get through my runes to cause me to stand up before camping finished...

Anyways... I don't use top slot as a swap. I've been considering it, basically by reversing the order of spells that I've always used in slots so that my top 1 is always a swap, #2 is often a swap, on down to my stuns and CC in the bottom. I'm sure I could get used to it in a week or two, especially since I'm still a bit out of a groove from my recent break anyway.

Buuuut it scares me to be playing without instantly-refreshed mesmerize/mesmerization. What do you top-slot-swap guys do when you're trying to get a charm break under control and one of the mobs resists your AE mez? Do you actually manage to reselect to the correct target and then cast a single-target mez before stun fades and it starts interrupting your casts? Do you just hope you have a stun off cooldown (I've taken to using flux-slant as a 1-2 punch on charm breaks to improve my chances of getting that first stun off without an interrupt during my time in POM, so I wouldn't have a stun ready in this situation usually)?

I (kind of) want to change, but change is scary!
