There is anecdotal evidence that the current power-leveling mechanism for gaining XP is detrimental to the Light & Full Party mechanisms for gaining XP. Producer/Director Yoshida can achieve the same effect that he wants, without the negative effect to Light & Full parties, by simply implementing a Level Sync system.

As long as gaining XP via power-leveling remains the most time effective means of gaining XP, systems like Light Party bonus, Full Party Bonus, even the party search system ... are pointless.

My question to Producer/Director Yoshida is, "Why build a system of balanced XP-gaining mechanisms, then allow another mechanism to completely bypass that same system?"

Personally, it just doesn't make sense to me.
