The known reason is that his contract was upto champions, after that they could have renewed it but didn't .

Assuming you are right here, why would they drop Hiro then? Isn't Hiro like a clutch sentinel/flex and since the meta is mainly towards cypher he would do just fine rather than signing a new sentinel player.

I have been thinking about it since the time he tweeted on him being a Restricted F/A. The player close to his calibre was Kaajak from Tier2 and now that Apeks has won and are a Tier 1 team I don't think Fnatic can pick Kaajak.

So who else is the potential candidate that can play duelist mainly Yoru, Neon, Raze as the meta is going to see more of these as duelists.
Any takes on this?
