Hey

It's mostly what Fire Main can provide as a supportive character, having him bring a pretty big Ninjutsu buff on top oft Debuff/shields is arguably uber. And something I wouldn't necessary recommend.

The issue with LM, is that he offers buffs for a specific type (Sword Users), and either he's a charka battery or acupuncture. Debuff clearing is better imo.

This is just a off the top suggestion reply, I'll let the team know and see if buffs are possible for the future.
