Bizarre Monster Book Error

That's not really a proper analogy. If your Hermit suddenly has maxed Double Stab instead of Lucky Seven, you're screwed. Your gameplay experience changes dramatically because you've lost use of an important skill. Monster Book is entirely for collector's value. It doesn't change gameplay. It doesn't cost NX to reset your stats back. When you sign on to the whole "collect them all" thing, you're doing so with the knowledge that the cards are worthless in the first place. They're not $100 and $1 bills. They're a Charizard and a Rattata.

I can understand why those of you that actually care about Monster Book would be upset, but personally I'd love if my Skeles got reset to 1 and a couple of other cards got maxed. Another hour of 1.15x on monsters that I collect way too many cards of anyway. I've probably wasted 5-6 Skele cards a piece.

On a side note, I've only picked up an Eye of Time monster card and that didn't change anything in my book.

"monster book cards are worthless in the first place"

Ok, following that same rule, levels are all worthless in the first place. Money you own in game is worthless in the first place. Quests you did are worthless in the first place. Monsters you killed are worthless in the first place.

This is a game. Everything you aim for is something you do that is worthless in the first place. Or maybe it's the opposite. While some aim for a lv 8 monster book, others do so for a lv 200 character.
