I know what you're thinking. I was a troll passing over a bow. Well, I didn't care for (what was then) +5 weapon skill. I liked guns. Even now that Bow Specialization grants 1% crit, I still prefer guns. That was just the way I want to play and I'd usually pass on all ranged weapon loot unless it's a firearm. This Troll Hunter of mine also has white hair and as a rule, only tames white pets. My stable includes the white bat Ressan the Needler, the white cat Sian-Rotam, and the white spider Leech Widow. The day Blizzard makes Aluntir, the white Silithid wasp, a tameable exotic pet is the day I spec Beast Mastery.
I like min/maxing as much as the next guy, really. But there are just certain idiosyncrasies with the way I play, such as my Shaman who pursued Goblin Engineering for the Pet Bombling. He's all about Engineering, so when Wrath comes he's likely to be on his motorcycle when on land and on his flying machine when in the Outlands or Northrend. Oh, he's got white hair, too, just like my Hunter and Paladin. It's just one of those things. I'm sure you also have little quirks on your characters or the way you play. What are your WoW idiosyncrasies?
