The problem with barbs is the same as pre-patch (except they are somewhat more aggresive, especially barb scouts - which is fine). That is the AVERAGE level of annoyance is okay, I'm totally fine with having to deal with a whole lot of barbs on the highest difficulty levels. However some games they'll hardly be a bother at all, other games I've had 3 camps throwing horse archers and horsemen at me at a frantic pace. So some consistancy would be fine. Maybe scale down the spawn rate of horse units until turn X or whatever, to at least give you a chance to adapt and clear out the camps before all hell breaks loose. Note that this is only a concern with horse camps, the other are fine and you're well enough equipped to deal with them with early game techs. Same goes for the aggresion level, which IMHO is good now.
