Set up a 2v2v2 match with bots, thinking my ally would make it easier to mop up the map.
Anyone who's played RTS with an AI ally can probably guess how that worked out...
I had no idea it was coming, either. I actually eliminated one AI, and was bearing down on an AI from the other enemy team, when both enemy teams sent forces at my base. They fought each other some, but were mostly happy to tear down my towers together. By the time my army returned, I had lost several production buildings.
On the plus side they were finally fighting each other. My army was mostly ranged, so I mopped up both sides without major casualties... Except bam, another wave just as large. With cavalry and ranged units making retreat impossible.
Well, for my army. My "hero" is a cowardly lizard merchant. Very high dexterity and charisma. My snehkpriests made them pay for every inch as my hero fled across the map, to my ally.
Fortunately I still had all my resources, and even had possession of the mines still. My hero began building a new temple-stronghold next to a couple of friendly towers. As I waited, I noticed... My ally had like 8 unit production buildings... But almost no units.
Cue the united enemy army swarming over the horizon. The towers were down in seconds - clearly my ally had not been attacked at all this game. Nor had bothered to produce an army. My hero fled to the other side of my ally's sprawling, completely undefended base.
The enemy army, having bashed down my ally's towers, razed out my fresh temple-stronghold... Then *left*. Not deigning to destroy or convert any of its buildings. Seconds later, it attacked the other side of my ally's base... The side I had fled too. Suuuuch cheating!
Technically I didn't die, I resigned. Which actually meant I got to keep the loot in my backpack, and avoided a hefty experience penalty. The game granted bonus XP for the high AI difficulties I'd set, and how long the round had lasted, not to mention all the XP for actions/kills I'd gained. So while I was defeated by filthy cheating AI and a braindead AI ally, I still gained a level.
Another point in dexterity and in running
