Their power grows exponentially during all the game, while they should be not so powerful in 1700-1800 as before. How can it be done: 1. Increasing stability penalty after 1700? Contested provinces become unstable, some stable ones become contested; 2. Making Janissary regiments impossible to upgrade? Increasing required amount of points for generating another one regiment? 3. Doing something to prevent of spamming with Pistoliers? (this is really annoying) E.g. increasing their building cost after each other is built. This will be useful to nerf other civs too.
