Enchanters own in general...such an incredibly fun class to play! A good charmed dps pet with 70% haste can almost double your entire groups dps at higher levels. Many mobs are underconned and can do insane damage/tank.
Charisma matters but you only get a small bonus to charm duration...it's much more important to be a lot of levels higher than the mob and to lower the mobs MR with Tishan and Malo(from shammy or mage). I have found that having a Shaman or Mage malo makes more of a difference in charm duration than the 241 charisma i now usually have.
I think you will really enjoy playing a chanter...it's a class where you are 100% engaged at all times, so you have to be quick on your feet. It's awesome for soloing or groups.
