You lost me there. Cav is underpowered, easy to kill and very fun to play against, since they dont really have ANY chance vs aware infantry. Obviously, rapetrain vs 1 guy is OP, but then, any gank 5 on 1 ends same way, unless the gankers are totally useless.
Woot good news!
Well, a single horseman, ever the worst kind, can be a formidable weapon on Siege mode, for the simple reason of the fast re-spawn timers, and this is proven from time to time there, specially on flat maps.
Any news regarding Siege are good news.
