I don't know if anyone would agree with me, but the change to siege weapons in BTS that stop them from killing any units is rather unbalancing, especially for large stacks.
I find myself often surging ahead of the AI in Monarch and sometimes Emperor on tech, just to find it impossible to fight against a civ with more land (more and ) because they have insanely large stacks of weaker units that I can't kill with my numbers (think 40 infantry against 200+ cavalry), using siege weapons won't help, since the large majority of units that you can't finish off due to a lack of units will have healed the next round and possibly gained some exp. This severely limits the ability of civs with little land from biding their time before war, lack of and not having enough cities for whipping/drafting makes it unviable to be peaceful for a long period of time.
