This issue exist for a month already and I still see people doing this.
Please read it slowly. In ranked battle, there can only be 3 generals but you can force 6 generals into the ranked game by following this instruction. This glitch is on a famous video in Youtube as well but no fix yet. This thread has been shown for almost a month and it was ignored by saying "CA CAN'T CONTROL" wtf ??
One more thing about the game balancing here:
I was one of the top rank in Shogun 2 Total war (and top 2% DotA2) and I can say.
Generals are too powerful in 3K causing the army to be just a tank and the meta comes out to be all the same. Heres the ideas of how almost every multiplayer game go ->
Xu Chu rekting any generals, Sima Yi silencing the map, no need Lubu as you can have 2 Xu Chu to rekt 3 Lubu anyway, and etc... There is no reason not to have 1-2 Xu Chu in your army. This needs some improvement otherwise the ranked game is so dull with no army strategy at all. Many ranked players also reported the same as can normally be found in Youtube videos. Btw, this also applies to single player battle as well.
If balancing is too difficult, at least increase the price of all OP heroes or reduce all their strength.
Thanks and good luck. Love the game and hope CA fix this soon.
