If i remember correctly crash damage was already nerfed by adding the shield bounce, but imo it's still a bit silly that czars and ahwassa's can 1 shot para's/smd's/etc even when they're shielded by 20 t3 shields. I know that these sort of strategies aren't that often used because they require a huge amount of mass but whenever i see it happen it still feel like me (or my opponent) is being cheated on.
So what i personally like to see is that shields would remove more crash damage.
Please don't use the "YoU CoUlD'vE InVeStEd In A AsF/SaMS" argument. We all know that one team is bound to win air control sooner or later (it barely happens when nobody has aircontrol for the entire game) and in the gamestage i'm talking about there's enough mass income to rush these t4's quite fast so asf to counter them isn't an option, and we all know that unless you invest an insane amount of mass into sams the t4 will still most likely make it through and fall on your base.
I know this is all very specific and i'm not saying we should balance around this idea (because it mostly happens on gap/dual gap games kappa (or the rare hilly or wonder)), but imo this won't change any other gamestage at all so it shouldn't have a negative impact (aside from people that use this tactic not liking it kappa).
I don't actually care that much because i very very rarely see this happen, but i still think it's something that should not exist in the game.
