NaturE's role on Gen.G

on the announcement of nature joining geng, people are asking what role he'll play, and 1 guy said he will igl and play sentinel, which is right.
here is what it says on his stream

Gen.G can't be getting rid of koosta, he's looked so good on the cypher and KJ, role swap maybe?

Options are probably just use a 1 duelist comp (shawn) or put koosta or mkael on awp
