I'd add that it's kind of waste to burn potions below a certain level.

For instance, using a pot to gain 100 ATK is quite a waste while in a few weeks/months you can use that same pot to recover 300 ATK. That make a huge difference.

At least, this is what I think, and I don't plan to use them before lvl 100.
