100T may not have a hard site hold style in mind though. They never have been so I'm not sure why you're saying it's gg.
100T are notorious for trap style plays and chamber is perfect for that as most kills chamber gets are virtually untradable as long as it's a hard anchor/low distance lurk. Additionally chamber is so good on maps for retake because it allows the player to hard anchor virtually any util, get a kill, and once again go unpunished
On top of this they would be able to always have info as long as chamber is alive allowing them to know general positioning from both attacker and defender sides.
Also saying yoru is a better chamber is entirely braindead. Tping away on yoru takes so much longer than chamber does.
Just because you play at an iron level on chamber doesn't mean they can't make it work lmao.
