Look at us, discussing gameplay concepts again here!
I guess I have to feel responsible for starting this discussion again.
And it might be a problem, because what's the sense of having a main character you level up if he's not getting involved in fights for the locations of the map ? As I said earlier, there won't be assassinations only, it's not possible to play on the epic and fighting in big battles. Also note a bunch of massive trolls can level up characters, equip them well, and start killing everyone in a village/town, just for fun. Can't remember if devs said if yes or not they'd punish these acts with bans, or do something against this.
