Severe Issues.. plz help

I need to know how to change the amount of exp. given off when a unit dies, how to fix my spellcasters so that they will cast spells instead of attacking, and how to fix the player races/colours, so that a user's colour and race is preset and unchangeable.
Make sense?:bgrun:

1) EXP: I think that can be done through the unit properties. Clicking the little square dot-thing button and clicking unit two times.

2) Spellcasters: Not sure, but I think thats hardcoded.

3) User's Color/Race = Present I think can be done in the players properties.

Thx. I'll try that...

Only the player properties worked, and i had that done already, its just that it allowed me to select because i tested it under single player...
Im making an AoS, and it still has those couple bugs left, and a real odd 1, but its real important that i turn the exp down, so that my heros dont lvl in 3 mins.

You can also check a trigger that sets a player experience gain from kills to a percentage... (Under Player - XXX I think)

Just thought of something. Was so stupid...

You can do that through unit editing, I think, if attack is an ability...not sure...never used the unit editor for a while.

Dead-Inside is right(Aren't you always my dear? =)), It's "Hero - Set Hero experience rate" Or something very similar to it. Set it to 50-75%, depending on how fast you want it to be. don't make it too slow, you can make a trigger like this:

E: A Hero levels up
A: Set experience rate for (Triggering unit) to "Experience rate of (triggering hero)" -6%

Or something like that. In other words, it makes it so that for every level a hero gains less and less xp, making it somewhat like Diablo 2 (The higher the level the more xp required, and less xp gained from monsters due to them becoming easier to kill)

At level 9, it has 9 x 6% decreased xp gain rate, aka -56%. You could make 6% higher if you think -56% is too little, or increasing the rate by checking the gained level and making several triggers for each level but that gets tedious to make... Hope it helped :)

EDIT:

That thing about the mages... I'm very unsure about this but perhaps you could make it so whenever they try to attack you order them to cast a spell... There's a large chance I'm way of road here, but I just got the idea. I won't take this further since I'm so unsure.
