I don't need alt characters for my different jobs. I play me and it wouldn't change if I was on a whole different character. I am versatile and reliable if people need a role filled. I want to tank but if a group needs a heal or dps I'm up for it.
Sure it's a pain to gear up all the jobs but my lowest ilv is sch at 103 and my highest is pld at i113. I take pride in that. Lots of work and dedication.
