I know that this would bring devs a lot of work but i think this would be great mod.
I apologize for my english.
It would be a 8v8 or 6v6 or 4v4 and it would be on a battlefield, there would be a large field where attackers and defenders would obviously be opposite at each other, at the start of the game there would start a intro and horses would rush into the battlefield, then starts the game and after like 60 sec would come the spearmen and after like 60 sec after spearmen would come ordinary soldiers with shields and swords and archers with ballistas would fire onto the battlefield all allong, ballistas would be controlled by an AI, so there would be 4 layers, first horses, second spearmen, third soldiers, fourth archers with ballistas, and behind archers would be a general that you must kill to win, soldiers will be spawning all time to cover the battlefield but you could spawn soldiers and spearmen to counter enemy minions and get to the general, how? Right next to general would be a board where you could spawn minions, minions would cost a points, here is example: soldiers=50 points (20 soldiers onto battlefield) horses=80 points (15) spearmen=90 (15) archers=90 (10) generals bodyguards= 180 (4) bodyguards would protect him at any cost by doing a body shields and killing enemies at sight, extreme good. I think this could be a good gamemode so let me know what do ya think and im aware how much work it would take.
