Ok so i half solved the problem of seperating kills for each character. Heres the thing. I got 6 characters that each player can play and switch between. I want it so each can level up. Now im stuck because at 10 kills i have it set for the player to level up with the unit hes playing. But if he switches to a different unit and get 5 kills and then switch back again to the original unit, how can i get it to continue counting kills for the original unit where it left off at 10..

i was thinking of having seperate kill boards for each unit to keep track but i dont know how to edit the killboard names.

Let's get this straight:

You want 6 units (classes) to level up separately, and each of those 6 units can be controlled by various players. Even if one player picks up the unit, drops him, and another player picks it up, you want the experience for that unit to stay the same?

Now, you want to have the experience displayed on the leaderboard for each unit? This last part is impossible to do well. The first is easy.

If my assumptions are correct, I or someone else will write an answer, and some possible workarounds. Please use the edit button for future responses if there are no new posts after your previous one. It's generally good form to not double post.
