Point by point:
1) I think if Shahz adopted Chamber from the jump, theres no reason he wouldnt of been good on the agent. If I remember correctly, he only played it once or twice professionally, one of those times with Dani as a sub.
2) You’re right, SicK and Dapr werent comfortable playing Sova, specifically on Icebox. Still, Dapr looked amazing on Fade during LCQ and I think the advantage of having Shahz on an OP agent outweighs the potential pitfalls of Dapr and Sick facing the initiator learning curve .
3) I agree, SicK on Raze and Tenz on Flex wouldve been interesting. SicK’s Raze on Bind was one of the best in the world.
