Has anybody faced or played as a ground troop that wears little or no armour on purpose? I think the Sarranids are meant for that. Wearing little equipment enables you to run much more fast, but since the Sarranids exist, they have a variety of armour that you can still run a good distance.
I honestly think that Sarranids and Swadians are equals. Swadians have better armour, but they don't move around as fast. Sarranids can move pretty fast, but it takes 2-5 cheap shots before a swadian goes down. Sarranids take 1-3 cheap shots, but because they move so %$&#ing fast, the player can simply move out of the way fast enough. I think when everybody has been mentioning that Swadians are better than the Middle-eastern/North-Africa faction, I think it's just most people have not yet recognized what the Sarranids can do.
