Chanter AC / HP vs CHA

[Halius]

So rather than start a new thread I thought I would just post here and see if anyone has advice. I am still pretty much a newb as a chanter and have been lucky enough to save up and sell things on my mage to buy decent equipment for my Enchanter.

Right now without buffs I have:

268 HP
555 Mana

68 STR
75 STA
119 AGI
100 DEX
83 WIS
131 INT
199 CHA

Would it be more beneficial for me to swap my 5 dex 7 cha rings for the 5 ac 55hp rings?

Would leave me with 90 DEX and 185 CHA but 110 more HP.
