If the experience point system gets an overdue and much needed overhaul I`d say yeah to the zerk/leave, but as it stands right now no way.

It's bad enough getting a crap hosp time for a zerk. Do you really want to use all your energy for a crap experience point return as well?. As it has been already been mentioned by other posters the gain would have to be significant to be viable.

Zerk/mug would pointless unless you were certain the player had a boatload of cash on them before you did it. Might be useful if it was introduced as an option to mug more cash from an established target as an improvement over the standard mug.

Zerk/ gang battle could be interesting but really has too many issues to be viable. It would encourage weaker gangs to attack stronger ones. Problem is there would be zero incentive for stronger players to use it so unless it is designed to have some value to the entire player base I don't see how it could work. In my opinion gang points really aren't that valuable anyway. Using all your energy for a potential 10 gang point gain isn't worth it.
