Metal ores: needed for bear banners, dragon banners, axes, bomb attacks, and time stops
…in other words, nearly every item you need for titans and monthly events; yet, for a 2* item they don’t drop nearly as frequently as they should. I know there have been complaints about the demand vs. availability of midnight roots as well, but for by comparison these are primarily used for mana potions, super mana potions, and bomb attacks. Still, they may be worth looking at as well.
Can the devs look into reducing the demand for these things? That 1 single mat should be required across a wide range of items is a bit ridiculous.
