To hero. Probably a neutral felar hunter/forester. Not sure about a cabal. Probably uncaballed unless I was really finding it hard to find groupmates.

Great survivability due to good hp and good physical defenses wilderness fam/dodge/archery/bait. Plus, camouflage lets you decide when to pick your fights. Obviously neutral to theoretically increase the number of allies.

Either that or a neutral arial assassin. Pretty much the same as above. You can pick your fights or hide away as necessary. Good defenses. I'd still prefer the felar hunter build though.

If I wanted to go a different route and go for speed rather than survivability it would have to be a human or half-elf/drow transmuter or healer. Neutral again to maximize groupmates availiable to rank with. Power to the hero ranks in a few days. With healer you have to contend with all sorts of empowerment issues. I think I might prefer the transmuter in this instance.

If all else fails befriend a lowbie Ravon and perma FTW
