Minions exist for us to get money or shield ourselves. I want the new game mode where you can upgrade the minions and control the minions, just like starcraft. Or the map of death match, you don't respawn once you die. Hope these ideas help you to create more interesting game mode. (Nexus siege was awesome)
there actually was Black Market Brawlers where you could upgrade your minions.
it was never seen in the rotating game mode queue, but hey, get ready for Round #315 of Poro King!
The map of death you mentioned, omg imagine there are 2 teams with 30 people or more on each side, a way bigger map, and once you die you don't come back (so it either ends the game for you and you can leave it, or you can still spectate if you want), and only the last one wins it. This is too exciting!
I've always loved the idea of a gamemode where you can directly influence/control minions. Unfortunately Black Market Brawlers was before my time
