Importance of INT gear for a chanter?

[Yumyums Inmahtumtums]

The depth of your mana pool really only affects kills where the enemy will take the whole bar or some sort of time-important raid event.

If it doesn't consume the whole bar then you are on roughly the same footing as other enchanters with 200+ int (simplified).

At the very minimum get to 200 cha. The difference between sub-200 cha and 200+ cha is astonishing. As I've said in other threads, my high elf was 182 cha unbuffed and exactly 200 buffed. The difference in charm lengths was unreal. Even if I wasn't laying attention I would IMMEDIATELY know when my cha buff would drop because charms became that much more unpredictable.

Tl;DR version: stack cha to 200, balance thereafter
