Chanter AC / HP vs CHA

[Diogene]

So I was sick taking beatings with my chanter, and thought I'd die less if I put some AC / HP gear on. So far a very nice improvement. I started to die less.
Currently at lvl 32, my stats are as follow with self buffs *:
470 AC
720 HP
160 INT > 1040 mana
115 CHA
70 cold R
70 MR
I'm not rich by any means, and usually dont carry more than 500p on me and in the bank...

I charm solo quite alot and learned to choose pets 4 or 5 lvl under me. My question is*: CHA doesnt seem to bother me right now, as I can still charm solo quite well with beguile (not so many early breaks) but how long this situation is gonna lasts*?? I love the idea of being a chanter with some good AC / HP's and a decent mana pool. But will the future prove me wrong*?
