I dont know, maybe im just a cavalry general at heart lol, when i go egypt i dont train camels after say 30 or 40 years, i stick to mamluks and ghulams cant have hurt since i won the game :P i know camels are strong against cavalry but heres an example of the flaws of most muslim armies.

Ive never seen chivalric knights be routed by BCW in my experience the charge of the cavalry kills enough camles that they are worn down and routed quicker than the cavalry are, the difference is the charge.

The armour isnt just about arrows defence, some cavalry just wont die whereas the camels lack of defence means sometimes even feudal men at arms can defeat them, ive just been playing as the sicilians against the egyptians then and my feudal men at arms caused mayhem, whereas if the enemy had charged with ghulams my infantry would have been surely routed.

Guess its down to preference in the end but i feel more secure with feudal or chivalric knights on my flanks than BCW in most situations anyway. :)
