For having already played these maps back in the days, I can say they are not that unbalanced. It's just that more people favors defenders (and eastern plated 2hcopter lagwhores). The one where the attackers get stuck on the first walls only needs a slight tweak so that the first point is easier to take but the other ones need to be harder. Ideally, points further inside the castle should be harder to take. I didn't experience any bugs, although it would be nice if the game could automatically choose a "good" spawn point every time a point is captured (leaving you the freedom to change it afterwards) and especially when the game starts.
