when I say passive, I mean pets that don't attack (learning from hh mistakes). I still feel like pets should be added, but that they give small boosts or perks, such as +1% extra damage, or pets that can slowly loot, or pets that are ridable and make you go faster.
another suggestion would be to add upgradable pets, such as making the boost go from 1% to 2% if upgraded (upgraded with money or gems, whatever is best), or making mounts go faster, or some pets loot faster. sounds like an interesting concept, and im open to what you guys might think.
