%Exp per kill
 

Is there a way to make the UI do basic math? I was thinking that we could use the spell window to make it into a percentage number showing how much XP was recieved per the last kill.

It seems to me that there should be a way to do this, but I am unsure of exactly how. Any help or advice would be appreciated.

How much xp is received per kill is not a number available to the UI, so the best you could hope for is to somehow take the displayed percentage, and keep track of when it changes. This is also something the UI can not do, but even if it could, most kills do not register a percent, so doing math won't help.

I doubt they will ever add anything like that either.
