Moving assassins into the city doesn't keep your control over the city, but it will allow you to gain a greater level of control. In a city with no assassins, your maximum control level is 50%. Each assassin added increases the limit by about 10%. That means it will take longer for templar influence to bring the city under seige.. Beyond that, you don't really gain anything from those assassins.
I need more Soldier Class Assassin recruits (Hidden Blade icon, Use medium sword and pistol). I noticed I mostly get Enforcers with some Marksmen and even less Scouts. I have noticed the all the "Assist Citizen" markers always respawn in the same spots later on if you saved from there before or whatever, and you can use the recruit system from the Mediteranian Defense. Question is, are there certain of those assist markers that garantees a certain class when you save from there or using the MD system and certain way to get a specific class, or is everything about it completly random, cause if so that sucks for me cause I'm trying to balance all my dens and have one of every class and an extra of the same class for the den leaders cause they cant go out of contracts. It's driving me nuts now cause I never seem to get any soldier classes and I need like 4 more of them, please help.
