Yeah, they did 'originally' have 2/1/2, but I guess they realized that was already taken up by war chariots. They really would be powerful if they had 2/1/2: being able to build them for 20 shields, so early, with no resource requirements (and resource requirements are pretty substantial this early), and not have the jungle/mountain restrictions of war chariots would make for a GREAT uu.
But no, they get the defense thing instead. I've never tried out bowmen, but they would be cool to try. I definitely know they couldn't do anything like has been done in this game, but with shorter distance to cover, they might be ok. Still, I'm not sure if you'd still want to build them once you can get swords and horses.
A 2/2/2 unit would be cool. A horse replacement could be given those stats. It wouldn't be as powerful as MWs, but would still be impressive. The Zulu can simulate it though, with impi/horse stacks, which is also something I'd love to play with at some point!
