You brought up another thing that just gets under my skin.

For the most part, Skill Breaks have set a precedence to require 4 star. However, there is quite a few Skillbreaks we have that CN also has that require 3 star (Sus Sasuke and 4th Raikage for example). When Oasis bumped them up to 4* requirement, it felt like a slap in the face to all f2p who got those ninjas and want to use them, but can't because they don't have the books they want.

IMO, SR's from treasures as the primary way in getting those frags, should only be 3* as a requirement. I mean Hashirama only needed 3* and Danzo, yet heaven forbid, Sus Sasuke or Ay 4th have them. I mean sure event ninjas to be added would be nice, like Edo Deidara at 3*, but by giving those event only ninjas breakthroughs, it gives players a reason to 4* them so they could Skill Trial them.
