you didn't watch much did u? chamber was already the agent of choice heading into the masters with his double trips, yay dominated the region on chamber then the world, literally the time period where the meta was started
optic was the only team heavily using chamber over jett in NA Challengers. SEN played optic once and it wasn't in an elimination match. it was not a chamber meta yet. keep coping
whether or not it should've been the chamber meta is something I'm not arguing. all I'm saying is that it wasn't a chamber meta, regardless of what it should've been.
