In larger team games it is just too hard to counter wonder. For example when playing on 4v4 maps such as Big Rock Bay (sry idk what it’s really called in English, my game is Chinese and that’s my literal back-translation), one of the opponents will always build a wonder at the top or bottom corner of the map. Upon seeing this, usually I’d need 2 minutes to adjust strategy and build many stables, 2 minutes to mass a huge army of horsemen along with trebs or cannons, 1 extra minute to wait for the soooo slowww moving siege units to slowly move to the shore, 2 minutes on transport ships to cross the sea, another 2 minutes to walk to the map corner, only to find 800 layers of walls and keeps and stone towers in front of it which is impossible to break through unless I have 10+ trebs or cannons. Launching another assault would similarly take 7+ minutes, this time facing a even more alerted and fortified enemy instead, and usually there’s only 5~6 minutes left after a failed assault. So essentially I only have one chance to do it, either make it or die. That’s just too lame of a way to end a game, no matter I’m on the winning side or losing side.
Seriously, the timer should scale with map sizes, such as 25 or 30 minutes for 4v4. The difficulty of destroying wonder is simply not the same on different sizes.
By the way did horsemen lose the ability to burn down gates at some point? I found it’s possible in Campaign but not in Skirmish, which makes destroying wonder much harder.
