Please, no more Materials in boss chests?

I like that you guys implemented a means to obtain Philosophy Materials in the new Lost City dungeon & Hard-Modes... however, having 1 Filtered Water drop from the Final Boss chest is quite silly & deflating, don't you think?

Just have them drop out of the optional chests only. Or if you do want them to drop out of boss chests, up the minimum amount to 3 & absolutely remove it from Final Boss.

In tandem with this change, please revert that feature in Lost City / Brayflox HM / Halatali HM?
