I've heard that chanters are comparable to Shamans in wow.

I am wondering about the dps of this character, Self Buffs/Group Buffs + Heals + Half decent Damage output (melee of course) = GG In my opinion.

Is this character worth playing? I just know they'll be needed in groups.

From everything I've read they are pretty decent support characters.

They are shamans but better, played shamans for years on wow and chanters always have their buffs up instead of having to worry about putting totems down when they move. Every group I made in Aion beta i looked for a chanter first, even their dps is good with a staff. They can also stay alive for a long time if the tank dies and they want to tank for that short time.

Yes i would agree chanters can tank and off heal when clerics are over whelmed. All though i have not played wow but yeah in aion chanters are a good class that can tank and heal
