Remove AEX from merchants on RP.

[shadowbomb213]

Wholeheartedly agree with removal. Speaking as someone who basically only played on 4, where there's maybe one or two rampages a month (from my observation! Could be wrong.) to coming to 3, I've already seen a bunch of AEX rampages. Quickly drained me, but I can't speak on others. Even if not a full removal, limiting them severely would make me much happier given that a half-determined antagonist can get so many at their current state.
