Warcraft 3 MODs

In the third one, I meant where should I look into if I want to change the xp rate of the server.
For the 1 and 2 , you wrote Know. But where do I need to fix that ?

I just tested War3ft on my CSDM server and I experienced a few problems that I wanted to change.
The chameleon race levels up but it won't let you choose the skill
The xp you get from assist a kill more than an actual kill

Also I have two more requests, can someone show me how to do it?
Can ...

Thank you very much

I didn't experience server that long because I just installed the mod today
I got this errors on my consol
