Been working on the AI a lot more this weekend as well. It is much more human now, and I had to make an "easy" mode for the bot.
On game start, during mode selection, there is a button to "Add AI". AI can be added, up to 4 AI per team, allowing for 7v7 matches.
"Normal AI" isnt amazing anymore, but stable. A good 5/10. Not really and cheats or special buffs for them, They stick to their side of the map, and occasionally boss.
"Hard AI" gets a little extra income still (not a lot). It will leave its side of the map to steal creep spawns. It attempts bosses more frequently, and kicks ass. A solid 8/10.
Both are more human like, and have less "well that was stupid" commands.
