TL;DR
Remove health bar status for rocksWhat ?
It might be quite useless this request but I feel that it needs to be tweaked because everytime I hit a rock or throw a grenade nearby I'll have a permanent rock health bar like on this screenshot:My suggestion is to remove health bar for all rocks and instead replace it with different textures. So if you hit a big rock, it get smaller every time you hit again until you gain rocks and coal resources from it. What do you think?
