For my main Zpan, who is an insane human hunter...I am honestly not sure o.O
Zpan is...feral and hardly what anyone would consider sane. She is a mercenary who is exuberantly violent and fond of fighting, drinking, explosions and profit. So maybe someone who can keep up with her and not try to change her? I'm not sure if she cares about what race her partner would be, even though she's very fond of waving gold coins at Blood Elf males telling them to strip and dance...but she probably does that to just piss them off. (she did learn to speak and read/write Orcish just to better insult the Orcs and Horde)
My little priest Maj? Well she's a young teenager with a massive crush on King Varian Wyrnn, so someone like him (or how she perceives him to be) - strong, noble, honorable, kind, intelligent, wise, ect. Then again, she's 15 and tends to blush and stammer when an even remotely attractive boy or man even looks at her or talks to her. XD
My Worgen warrior Marguax? She'd like someone who doesn't view her by her curse - she hates her curse and spends all time out of battle in her birth-form. She'd never go for a Forsaken or Death Knight though. I'm pretty sure she's straight, even though getting a guy to look past not just her curse but also her masculine appearance...would be on the top of her list of must haves. I doubt she'd be comfortable dating a Gnome or Dwarf given the size difference...she'd like a guy taller then her.
Hmmm. My Human Paladin Barthe? Given his upbringing would look to marry either another paladin, a priest, warrior or civilian. Probably would only be interested in another human or Draenei. He'd look for a woman aligned with the Light, noble, trustworthy, sweet-natured...
Lucek, my Human Warlock would probably only be interested in a human woman - one who is sweet-natured and would be someone he could trust completely.
My human rogue Musei....errrmmm....well someone who finds her attractive despite the fact she's horribly scarred up would be a big plus. I doubt she'dd ever go for a Worgen given he scars were gain via a near fatal dog mauling when she was a kid... I've not decided her orientation so...she probably wouldn't care XD
