Dennis brings up some good points, the reason why encounters require supervision is so, as Dennis mentioned, people don't hop on a job to kill someone and do it under the guise of one of these "random RP" scenarios. If you're able to present a good way to circumvent this, and some of the other issues this presents I'd definitely +1. As of now, this idea seems to just be encounters that don't need supervision, although you would still need administrators to help with the scenario anyways(health setting, load-outs, getting out of admin room). Currently VIP's can just ask to get supervised if they want to do an encounter, although I don't know how many know of this as it doesn't get stated anywhere obvious.
For now, its a -1, if you address some of the grievances I listed with adequate explanation i'd definitely change my vote.
