Mentioning equip rates and introducing more rng to the game both trigger me but on the whole these changes have a bunch of potential. I like how valve are basically officially telling us that the eviction notice is the baby gru -- while it's a bit lame to have two unlocks that do basically the same thing just to a different extent, this game has so many weapons that it doesn't really matter at this point. Some of these new mechanics are really cool ideas as well.
That said, the gru changes as I understand them will do nothing for their main issue, which is running heavy to mid. As long as you're aware of how long it takes for your health to regenerate and ensure you don't die before that time you can still use them to bring cancer to otherwise arguably the most fun fight of every round. The crit-a-cola changes are also potentially not a harsh enough nerf but it's still better than any of the previous iterations I can recall.
If these balance changes get released with hopefully a few tweaks along with proper matchmaking fixes this game might actually not be dead quite yet.
