I like rust but I would like it to be more cooperative.
I wonder whether this could be achieved by allowing people only to learn a certain number of abilities, e.g. 10 abilities. You may learn more than that but would lose your oldest ability (or the one you choose?). There might be some kind of experience, allowing you to learn more (or more difficult) abilities. For hardcore gamers there could also be a rule /option that you lose one ability if you die.
What do you think?
