Increased Rates

[The Roger]

Jokes aside, manually increasing the droprate of cards directly on monsters could be a viable solution; as mintt suggested.
The advantage of this kind of operation would be able to tweak up greatly the % on useless/semi-useless/pseudo-useless/hatter cards, tweak a little the somewhat-useful cards, while keeping unchanged at 0.03 those cards that are good/very-good, mvp and miniboss.
Facing the reality, all the first category cards (which arent hatter) are already dumped in storages and not traded in the market, so it wont hurt to increase their %. Half that for the semi-good cards, which see little power-increase if used. Good and strong cards must stay at 0.03%.

Examples:
- Wormtail card 0.09%
- Archer Skeleton card 0.09%
- Dark Frame card 0.09%
- all the class-combo cards 0.09%

- Alligator card 0.06%
- Loli Ruri card 0.06%

- Zipper Bear card 0.03%
- Green Ferus card 0.03%
- Zerom card 0.03%

edit/ps: if we actually end doing this, then going to increase the world-droprate would have extreme effects on cards at 0.09 becoming nearly 0.2% and those at 0.06% becoming 0.12%. So, we should keep this in mind.
