I do as well, but they're incredibly rare, myself included. People are usually shocked when I join a duty and they see their healer is a male Roe. At this point, I get excited just seeing a male Roe caster. Since there aren't any restrictions with race/class, I'm not sure why some people feel like "Oh you're a big Roe guy, so you should be a tank or melee DPS".
Ugh.. Rant over.
