I can root rot solo in there. It can get a bit hairy, but not too tough (depends on your current gear obviously). Duoing with another root rot class would be nice. Shm with necro/druid/shm or maybe even ranger (i dont know much about bows) would work well.
If you wanna tank stuff.... that's a little trickier. I suppose that would work with a high dps melee class with good gear (and don't forget to snare). Buff with the gear/aa require to tank duo in there efficiently, RS prolly won't have too many upgrades for you there :p
Edit:
Looking at the magelos of the person who started the thread, i would say you could defintely pull it off. I've healed a sub 10k pally tanking there, i'm thinking your 12.6k zerker will do well, snares too! Balance of discord and VS would be important to get for your shaman to heal/slow there. Discord slows a RS trash mob about 95% of the time on the first hit, fire VS if it resists. Only problem could be geting 2 at a time or adds. Keep MD/VP up for adds and you should be fine.
