Let's just forget about what happened and be optimised in the opinions.
See If Wardell Played JETT and Corey played second duelist, then they would lack a sentinel player in most of the maps.
If Corey played Chamber as a sentinel then Wardell shouldn't OP which is his greatest advantage.
If Rossy plays a Sentinel then Subroza is stuck on Smoke.
Is it that they can't get a Composition for each map which suits the meta.
And I think Corey needs time as a Jett player.
See Most of the Jett mains that i have seen are a little cracked in the head except D3FFO.
Corey is a bit optimistic/ bringing less value to the team on defence and on attack as well.
They need more time. I will be happy if they don't disband and spend more time and show some chemistry. Cause at the moment they lack chemistry and firepower even after having such good talent.
