To give my honest opinion on what @Ueda said in that clip.
If he wants to continue having the sub-path masteries available without locking them, then there needs to be done some serious changes to them.
Things that should be done to create a balanced hybrid system:
Level 10 Bubble Pipe should be nerfed to the ground.
Level 20 Bubble Pipe with much higher (40) strength requirement should be added. This pipe would be what the current level 10 pipe is in terms of ability.
In order to be a hybrid and to use the powerful tools you should be forced to sacrifice more stats.
Level 10 fan jutsu should be swapped positions with the Level 20 or 25 (the long piercing one if I am not mistaken).
The wind users who want to use fan jutsu should also be forced to invest more stats in order to use the more useful jutsu.
- This is the way that I think is one of the few possible to somewhat balance things out -
