((Saying that the rebellion should go ahead because even if it turns out to be a crappy government, which let's be honest, it will be compared to Carrion, it can always just be taken back by Carrion, is quite frankly ignorant. If you do prove to be a crappy government, then you'll be a crappy government built upon shattered foundations due to the rebellion itself. Then, Carrion will have to try and fix that once they would take the throne back. You would be putting Oren into a time of chaos because you want the crown, and a chaotic Kingdom is bad for RP, especially if it's the Kingdom of one of, if not the single most, active race in LOTC.
No it's not worth it, but quite frankly, I'd like to see a war to get involved in, and with both us Orcs and Oren against your rebels, then it should be pretty entertaining for us at least. So go ahead, but don't win. :D ))
