@Colombiadragon that's exactly how I did it on missins that i didn't wanna open with summons
Since the summon changes it's almost impossible to save melee heroes from dying and moraleboosting the ennemy forces.
Placing all melees close together and summon a bunch of troups in front of them saved them most of the times but now they just die, dunno don't like it.
I think the summon nerfs are very reasonable btw, but melee heroes either should't run to the front all the time (increase melee hitbox) or not get targeted if other troups are around. I don't think increasing their HP would be great. Frontlines are tanky enough in PvP and immortal heroes aren't great either.
