i think we need characters that have selling effects or on death effects, and maybe more on kill effects
i also think we need guys that obviously cooperate with each other and make combos:
ie 'kill in lane heal allies by 1' + 'when healed deal healed damage to all enemies(or lowest health)'
buta anyway id like to see some stuff thats similar to super auto pets: its really good and just like this game just with more content(one drawback is that upgrades are underpowered and characters sometimes have useless abilities)
