Stick with him. Another preseason, dozen games and some healthy competition will push him to the next level.
Lets not forget that Cam McInnes wasn't an exciting hooker, he was very much pass and tackle. From what I can find, McInnes' best attacking output was 4 tries, 6 assists in a season. Coincidently, the same as Blake produced last season, his first full season starting.
I would love to have a hooker that can spark us and control a game, I think Blayke could get there as that guy but agree he is a way off it yet. However, if we start looking for answers at 9 in Cam I think we will all be disappointed. McInnes will be a fantastic 13 under these new rules, I really want to see him play there.
