Advanced war
Many players have a substantial amounts of cats. It is difficult to get to those and feel that it should be a bit easier (like having squares and you can move around and they need to protect their cats -more-so than just a red line on the field). OR if I have a ton of cats, why not make it so I can split them to attack multi areas at once.
Finally, why not make a random ground to slow or give advantages to different parts the field. -everyone moves forward and that is it- (Art of War stuff) There is no high ground, or anything that can make it possible for a player to win if they have less resources. Many times in war, you can have a few troops do a lot of damage, if planned correctly. Currently it is all about brawn not brain. Don't take this as me saying 1 guy could kill 10 horses, just think that there should be a way to out-think your opponent.
