For Ototmans would it make more sense for Azabs to have option to be SUGs especially as behind barricades they don't have to run away. Makes them less tough but means easier to do typical Ottoman tactics of letting them be chaff to wear down the opponents and not be bothered about it. Making them TUGs means that their loss does contribute to army break level?
So as at Nicopolis the Crusader knights broke through the Azabs to get to the Janissaries
but the Ottoman nerve held and they routed them with an ambush
Would encourage historical Ottoman operational strategy- go on offensive but in the battle pick defensive position and force the enemy to come to them
I think this could well be a good suggestion - but I'd not claim any great knowledge about Ottoman warfare.
