Bots are dump and predictable. You should try playing normals, it has so much better depth and strategy than bot games. A game without challenge isn't fun at all.

On topic, making "hard" bots isn't an easy task. I'm a programmer that has done research on AI stuff and isn't trivial. Most bot engines basically "cheat" to compensate the lack of intelligence. Often bots have complete vision (no fog of war, wallhack on FPS games) or instant reaction times. But they're still dumb. On a dual lane, one of the human players can get low health and bots will blindly chase for the kill, while his partner kills them. That's because the weight of the agressive action is higher than the survival one.
