Excess Monster Cards

Hi MapleLegends Team!
I wanted to see if anyone brought this up before! I would like to recommend that any excess monster card that drops when farming could be sold in stores for Mesos or in the Auction house! A lot of people (new people) are looking for ways to make mesos in the game! Adding this can help a little with that. People are always trying to card hunt for their Monster Book Ring! Why not let it be a community thing as well?

Once someone reaches 5 cards (a stack) the next cards that drop will be put in the etc. tab of our bags. We can either then sell them to the shop or sell them in the FM?

Let me know what you think about this?
