Basically, Fatimids and Ayyubids are based around k_Egypt. That's the kingdom-tier title the Caliph/Sultan holds with which he holds all those emirs as vassals.
A strong European feudal ruler can disestablish Egypt within one long reign. Just get to 50%, usurp k_Egypt. Even if someone eventually usurps/forms it back (e.g. succession, losing a holy war or two), the emirs outside Egypt won't fall back into vassalage. The blob is over.
For a republic, this is impossible. Fatties reduced to a small patch of land are still around, still hold Mamluks as vassals. A crippled de iure Rum would still have Gilman as vassals. This is not bad from the POV of their defence, but it's worse when they can use the merc stack (plus like 2-3K levies) to fall upon OPM's such as rebel dukes/counts or recent independents. And blob back to size.
Please make it possible for republics at least to destroy someone else's kingdom/empire title if they can't usurp it for themselves.
