So I don't think all the Muslim heavy cavalry need to be able to defeat MS's by definition.
Also, I was originally very confused that units like Ottoman Sipahi or Ottoman infantry, though not available till late, have lower build requirements and stats than Ghulam Cavalry or Turcoman foot. Now I think of them as Turkish expansion units. It was during the late period that the Ottoman Empire overran the Muslim world and the Balkans. With the lower build requirements, Ottoman troops can be built quickly in conquered provinces with less infrastructure, so they're quickly raisable troops to defend the frontiers or push them further, not so much elite as readily available.
Mamluk cavalry really disappoint me, though. I don't think I've learned to use them to their best potential, but still they feel seriously lacking in punch, especially for the kind of unit that threw off the Mongols and ruled supreme in the desert. Not sure what should be changed, but if any Muslim Cavalry unit needs improving this is the one I'd pick.
