My GF and I always joke about how she is selfish so she has always played a warlock, being a DPS and not necessarily "offering" as much to the raid. On the flipside I am supposedly selfless because I have always played a tank or healer (paladin/druid/shaman) and my stint as a DK DPS didn't last long at all.
What are peoples' opinions on this? Do you think your personality manifests in-game beyond how you interact with others?
