I couldn't agree more, this is why I play my Paladin too. I have so much more fun playing almost any other class, but I've put too much time into this Pally.
I do not relate to that sentiment at all. What does that crap matter? You guys outta play the classes you find the most fun.
I do play the classes that I find the most fun. You typically wouldn't see me on my Paladin unless I was doing dailies, raid, RBGs, farming, etc. My point was, if mounts, vanity pets/items and achievements were account bound, my Paladin would be SO dusty.
After years of "main-ing" (for a lack of better worse to use), for me anyway, it gets boring. But people trust me to do my job, especially on my Paladin...so I'm kind-of stuck. >.<
