well tbf summon cultivation and the actual combat pet are 2 different systems they are connected yes but not exactly the same system, what im still missing from 3.0 are the red chakras in the 8gates shop because that would also mean yellow init chakras there, also the skillbook changes when the tsunade npc comes wont make many players happy ^^ yes you can reroll skill books you already have than but you need to spend seal scrolls there to draw for books also as far as i know that also means you cannt buy skillbooks for ninja fragments anymore when that update comes
