The drop rate enhancements (for Zel, Karma, and Item drop rate) won't change much since they're dependent on hits. With Zelnite as the lead and with over 100 hits in your squad (which is very easy to achieve if you have multiple Larios), you statistically have a near guaranteed chance of getting the rare drop.

For any chance that you can summon Zelnite, I'd go for it. He's one of the best units in the current metagame since his role fits so well in practically anywhere.
