I'd say 7/10 could make a decent high level staker, stake mages and pwn them with Iban blast. (needs a bit of work though)
And to the people that think rsc = crap, it's only because you started after or around the time of the switch over. I know for a fact that those of you who spent hours and hours of your childhood or young adult lives in the mining guild, questing, staking and/or pking would go back in a second given the chance. It's something called nostalgia.
