Well, for me as a Vitality fan, I'm pretty sure that Cender can play duelist, he proved that he can play well as an Operator main multiple times, that he can also riffle, that he can play Chamber (tbh Chamber is more duelist than sentinel) and if I remember well, he also played Jett a long time ago. Imo, I really think that he can fit in duelist role and if that happens, H1ber will be benched. With that move, Nats can fits in the team as main sentinel and can also plays double controller on some maps with Baddy on Astra/Brim/Omen while Nats plays Viper. Moreover Natank isn't even in the discussion about it, he plays more like in a support role and well, Baddy and Bonecold are untouchable.
