Saying "I have a healer alt" is the MMO equivalent of saying "I have a lot of black friends."
I didn't read the OP so if there was some whining going on here, I'm certainly not part of it. Very often however the only time people care about healers is before the match so they know who to guard for medals or after the match so they can vote for MVP. Between then the healer is left to keep itself alive and make sure you have fun. Appreciate that.
