[(Theoretically) What new playable race do you want?]

What? No love for golems?I'd love to play as one of the asuras golems.You'd play as a new type of golem controlled by an asura golemancer who's stealthed for the most part. When you're doing story stuff he/she would pop out of stealth and act just as any asura player would.Would require very little from Anet, as they wouldn't need to add a new map or story, and it wouldn't clash with the lore as there's golemancers all over the place already.

[Eater of Souls fight is too difficult.]

If you're a necro you can easily beat it by equipping all minion skills and let them attack him while you're 901+ range away. If you can attack him with your scepter you're to close and he'll rush you, stun you and get full health.
