Wait why are we in B/C tier?

I don't know how relevant streamer tier lists are but I trust Teamcaptain's most of the time, since he's a reliable source for high level play.

so, he put Hawkeye in B tier, others put him C and even D....what happened? it's not like he lost the ability to 1 shot.

I know he gets easily countered by Dive but that hasn't changed since season 0, what's the difference? I've always saw him in A or S.
