why play cned on raze when he is clearly not comfortable on it
I think its combination of many things. cNed isn't very flexible. Shao can't play Skye. ANGE1 doesn't seem to like playing Brimstone, Astra etc and priorities his own comfortability. And you already have a mess in this current meta.
And the frustrating thing is that NaVi spent most of their split experiementing with some shitty one timer comps instead of playing roles that truly make sense. Surely cNed's time was better spent on playing Yoru than getting more comfortable with Raze. Surely ANGE1's Yoru was more important than trying to make Shao learn Skye etc.
People talk a lot of about cNed/Zyppan Raze, but I also think they are getting giga fucked when their main initiator player isn't playing any Skye. That is why they stick to Zyppan Skye every map.
