Maybe it's just me, but spawn seems like it SHOULD be the safe space, once you get there, nothing else could really do much, and shutters are LARGELY frustrating, specially if a teammate tries to get out of spawn at the same time you're being chased. Also most spawn doors have a long way from the cabinet to the door, which is fair in the sense of making people not just stand by the shutter all the time to get health back but it slows down gameplay a lot of times for no real reason aside.
I'm all about reducing dead time and making spawn shutters less infuriating, so i wouldn't agree to ban that bind, but that could be just me or i'm thinking wrong about it. The thing is that i haven't ever had a problem with my opponents using it against me either, really, so i dont see why it should be gone.
