I am aware that someone suggested classes. And I think it would be interesting if you could adjust things a bit. For example, you could use a slider to give yourself 1 or 2 more grenades but would require that you take away some bullets or something.
You could maybe get something like 100 inventory points total.
This would be divided among the items in your inventory.
----GRIEFING ISSUES----
Someone could make their grenade partition 99%, which could mean serious griefing. This would mean there would have to be some kind of limit.
Post what you think and how this could be better.
