Seriously, why Bladestorm and not Avenger? I find Avenger more appealing. Or what about Duelist? Or Fencer. Or Slayer. Or even Orc Slayer.
I'm sure elves aren't too fond of big ugly orcs, who'd rather die in fire then live in harmony.
I might be not the best judge (because English is not my native language), but I think "Bladestorm" really don't sound too well.
