I have a confession: I don't like respeccing.
I think I have only paid to repec a couple of times over the entire length of my WoW playtime. It just doesn't sit comfortably with me. Guild mates happily respec their characters from second to second, to create the most viable minmaxed character they can, but I stay away from that "I'd like to unlearn my talents" dialogue option at all costs.
Well, I'm cheap, for one. I've been perpetually short of gold since I started killing spiders in the branches of Teldrassil and I've never been anywhere near wealthy since. I started the Burning Crusade in debt to a guildie for my Epic Mount, and I'm concentrating on getting my Epic Flight Form ASAP without taking a loan so I don't start Wrath of the Lich King the same way. So, I just don't have the cash to do it that often.
That's not the only reason, though. It just doesn't sit right with me. I play on an RP server for a reason, and the idea of a characters skill sets and abilities suddenly switching around because the raid needs a tank rather than a healer just doesn't sit right with me. I know my skill set, and I know it well. I know what works for me in PvP, solo PvE and grouping. I think, for me, that I'm happier working with one less-than-perfect spec, than constantly switching specs around just to meet the needs of the moment, and then having to relearn (or adjust) my play style.
So, how about you? Are you a respec addict, or a mono-spec loyalist?
