I'm not a huge fan of half-races in general. I'd just as soon everyone play full-fledged orcs and elves.
However, "wilden" remind me that 4e loves dumb names (there was something wrong with killoren?), so I have to vote it down out of protest. I also think the fluff -- "we awoke to fight off far realm critters!" -- hurts my desire to keep my far realm, well, far away, alien and eternal, like the cthulu that inspired it.
So, ultimately, half-orcs suck marginally less.
