I guess many of us players are just as forgetful about the leveling experience as the devs seem to be.
At level 52, you'd be limited to Midare only. Higanbana, generating only 5-10 Kenki over its Sen generation in ST combat, and Tenka Goken, generating only 10-15 Kenki over its Sen generation in ST combat, would be impossible to cast. That or you'd be forced to spam Enpi to make up the difference. And all that's assuming the Samurai lands every positional, else they can't even use Midare until having overridden as many Sen as they missed positionals (or, spam Yukikaze).
You don't get anything like current Kenki play until level 62. The two experiences are worlds apart.
