Are there going to be specific enemies that attack certain targets? Or are they all just going to go for the closest enemy? Cos it would make it interesting if some had specific enemies, like, kamikaze enemies that go straight for the thumper to deal massive dmg but have little hp and def, long range enemies that attack units in the air for moderate dmg or enemies that swarm the player that attacks one of them when hit or killed or explode dealing dmg to enemiesor debuffing (eg bleed, slow or prevention from jumping/gliding). Along with the standard tank unit and others.
