I don't know what you mean when you say "relevant" mob. I tank mobs all the time without healing support - but i suppose none of those are "relevant" in your opinion
Anyway, i'm getting tired of this silly argument. Play paladin like you want. If you don't want to heal yourself with your paladin then don't. If you want to be a dps with your paladin, have at it. If you think the job sucks and every other job is better, just play a different job. I don't see us getting anywhere on this, cause we aren't going to agree.
