If you don't want to heal, then don't ever play a class that is capable of healing. Period. If you play a class that is capable of healing, people will expect you to heal, especially the minstrel class. For the following reasons:
The minstrel in WS is super fun and great AoE DPS, but at the end of the day, it's not a sustained dps like a champion or hunter, and it's not as much of a burst as an RK. So while it's great for solo/duo/3-man/easy 6-man, it's really not good for anything else. People won't want mini DPS in harder group content or any raids because the single target dps just isn't there, and the AoEs are an issue in any situation where you have crowd control or are not able to AoE due to the mechanics of the fight. That severely lowers the overall DPS of our class. Because of this minstrels are usually expected to heal in any end game raid or harder 6 man content.
