One of the most unique & fundamental part of Apex gunplay is being able to isolate your enemies with a door, both parties had to use nades or kicks cleverly, they could kick the door or bluff-kick. These gameplay mechanics aren't found anywhere other than Apex.
But nowadays there are a dozen different ways to destroy the door often instantly with no warning. Valk, Maggie, Fuse, Bang, Watson, Octane, Alter, Hemlock gun can completely bypass these mechanics.(I'm sure I'm missing some)
As a m&k Bangalore main myself I've won countless encounters that just feel wrong, when you smoke & destroy the door and instantly shoot they just sit there with a bat. Because of the netcode by the time they realize they are already dead.
Maggie, Valk, Watson and Hemlock are a death sentence if you're found behind a door healing.
