Okay. Overall, there's something very fun about murderhoboing that makes it attractive to new players (Maybe it's the agency with no consequences). Additionally, the game seems to push people to murderhoboing, probably the "being made out of XP", which is solved by using not using XP (I'm sure there'll be tons of murderhobos still for other reasons, but the orc=xp thing seems like a major factor).
Murderhoboing is hard to handle. I typically play with newer players, who seem to be more prone to going around and murdering anyone and taking their stuff. First, I would talk to them. Second, I would kill their character, or give a severe penalty to them. Once they see there are benefits to not murderhoboing, it's likely that they'll stop, or do less of it.
I am all for playing your campaign how it is fun for you, but there is such a thing as a "problem player", but they normally depend on the table they're at. I think if D&D had a ruleset on XP awards based on roleplay, I think less people would be murderhobos, but the problem is also definitely deeper than just creating a new leveling up system.
Are there really DMs who award XP for killing random shopkeepers?
