I don't have Warlords yet, how're trebuchets? I assume they fill the insanely long gap between cats and cannons, it was always interesting to march to war with rifles and cavalry and catapults (realistically cannons should predate musketmen but whatever). What tech enables them? How strong are they? Also, are they the only new nonunique unit?
Also do Janisaries get a bonus vs. mounted or just archers and melee?
