Well then I'm sorry I bothered you. It's quite an old problem now actually, I found the DotA source code, and from there I've been able to construct a skilled AI. Like I said, I just heard from someone that you were good at it :S guess they were wrong.
I guess the AI competition did kinda die out. Maybe they'll do it again sometime, I'd like to join this time
HoN IS DotA, they actually asked Icefrog about it, too. Like 90% same heroes, just different names, models, effects, etc. But it's smoother and more advanced, so obviously HoN should be more fun. And they have 3 maps currently, not just one, and a few of their own custom heroes, lol.
Ow, well, maybe fix leaks, null variables... If your map continues to work over 9000 then there's not really much to worry about. The lag could come from the units and mainly from corpses. I personally have never experienced lag and with my testings I started getting huge lags around 400,000 handles... I don't know, I'm not really an expert.
It's actually quite normal - the game is allocating new handles and should free them at some point of the game (actually, when you free them ). If they're bellow 8191 then there's nothing to worry about. If not, then you know the usual problems that might happen depending on your systems.
