I read a post from another player and they mentioned how the Fallen don't really use the walls and ceilings like they should during combat. When they fight the Hive both factions have the exact same behavior and strategies. It is a ton of fun fighting both sides but I wish they changed the behavior so the two would actually look different when fighting them. I agree I think the Fallen should naturally climb up walls and fire at you like those bugs did in Halo! That would be challenging to avoid and make them seem more like a different alien race then just a reskinned Hive. Thoughts?
