Ghazis are only good as flankers. You need to use them in conjunction with the Saracen. Once the MHC turn and attack them, they are done for.
Granted, granted. I also typically bring 2 units of them to battle - one for each flank :D

I also once tried to hide a unit in the forest for an ambush against the Golden Horde lol. I don't remember the details but it went very bad - they were charged head-on by a full unit of MHC and lost half of their men + routed in a few seconds...

For Turks, Futuwwa + Saracen Infantry = win until you get Janissaries. However, for Egyptians, I did not even know Nizaris existed lol. Do they require some high tech buildings? I have played Eggy but I never remembered Nizaris...

What's the difference between Turcoman and vanilla HA? I as if remember HA were better about something (was it morale?)
