Yeah like everyone still gets whatever exp they normally would they just get it in the group, and the lowest level player dictates the level you can kill for mods and exp.
So if a level 40, 80, and 275 were grouped together.
There could be a * by the 40. And now the exp and mod system goes off level 40 and if you kill anything 40 levels higher wouldn't garnish any xp?
I'm sure theres a way to put a simple check in once someones in a group to help make this viable.
With a lower amount of players being able to group together and play together keeps people coming around and rping, and having fun and that is something that should be a top priority ATM.
