Why you want to change the meta already? When you said it yourself f2p has to piece premium ninjas in time? Not everyone get lucky and can have Shisui for free.

Shisui is out for 3 months now and it's a decent amount of time for MAJOR of players no matter f2p or casual p2p who didn't get lucky in rng event to piece him up. That mean most of them just got Shisui for 1 or 2 weeks. And you already want to change the meta? Can you just think about everyone else and not yourself for once? So what you gonna do next after they release SS Temari? Cry about the SS Temari meta and demand Hiruzen? Then what you gonna do after Hiruzen release? Cry about it and demand Ay4 bt? Edo 3 tails jinchuriki?

meta stale? I don't see it, the meta is fine. High bp players still using various mix teams even if they are using the same core ninja. You want to chase away f2p and casual p2p? This is how you do it. Congrat.
