Idk where you heard that it's f2p there are hyping, don't just make stuff up or that it's because of Han/Tobi/Minata but personally for me biggest things to look forward too are not the the ninjas.
1. Sage World give rewards to top 10 not top 3
2. Ninja exams to 180
3. All pains in exchange shops + Sakura/papa Shika, i have hundreds of thousands unspent coins waiting
4. lvl 95 level cap, more story
5. Costumes finally show in fight
6. Blacklist should properly block people now
7. *Maybe* tactic pages in group activity, Germany had this before 3.0, but just wishful thinking on my part that we get it about now lol
