Most boring faction to play as

[Ibrahim]

You need lvl 4 regional MIC for Pilei Ya'ar Libim (the small ones) and lvl 5 regional MIC for Elephantes Liboukoi (the Bush Elephants). IIRC, Indian Elephants require lvl 4 regional MIC. Thus, Type IV government is probably the best for elephants.
By the way, be careful when using the Elephantes Liboukoi. Although they are at least as powerful as the Indian Elephants, their morale is extremely low (4, which is less than half of that of Arab slingers). Fortunately, government types III and IV come with a +1 experience bonus for Saba.

thanks! *goes off to save the war effort*
