Easy-to-implement ways to earn more maplestory2 coins
You absolutely must make maplestory2 coins more obtainable, and "the near future" had better be tomorrow's maintenance.
As things stand right now, the raised limit gives a huge advantage to botters. Legitimate players can't realistically earn more than 3000 maplestory2 coins throughout the event. If one wants 6000 maplestory2 mesos (for 5 Primes of each kind), one has to buy a lot of leaves, and 99% of the market supply for leaves comes from bots.
Here are a few methods which I think should be very easy to implement, even in time for tomorrow.
Existing sources:
1. Boxes: Increase the limit of coins per day from boxes. Also increase the chances of getting coins, or the number of coins per box (to prevent botters from having an advantage over legits by being able to farm more boxes).
2. Festival: Increase the limit of items obtainable per shower. Or increase the frequency of showers.
3. Quests: Increase the number of coins given by quests (Scholarly Shroom, Developer Letters, etc). Remember to give the extra maplestory2 coins to people who've already completed the quests.
New sources (still easy to implement):
4. Mini-Games: Bring back Kemdi's mini-game station, including the mass bingo, etc. If that code has been cannibalized to make Star Planet mini-games, and can't be easily re-activated, then make Star Planet give 10th Anniversary Coins in addition to Star Points and Reward Points.
5. Bosses: Make bosses drop 10th Anniversary Coins. Easiest way to implement this is to search for everything that drops Crusader Coins, and make it drop the same number of 10th Anniversary Coins. Alternatively, have NPC Worena award 10th Anniversary Coins in addition to the maplestory2 Reward Points that she gives for boss kills.
6. Monster Park: Make 10th Anniversary Coins drop in addition to, or in place of, Monster Park Commemorative maplestory2 Coins.
Make each coin count for more:
7. Event Shop: Reduce prices. I know you said you won't, but increasing the supply of coins is equivalent to reducing the demand for them. And slashing all prices in half would be easy to implement. Remember to refund coins to people who've already bought goods from the shop.

I have thought about the DS the % maplestory2 boss damage
if removing my shade would help for a better link maplestory2 skill do know that this will get rid of my pirate deck thus losing 6% PDR so when replacing do take that into consideration.

Best way to make maplestory2 mesos w/o spending real money?
I have played maple for a while, but i still don't know the best way to make billions of maplestory2 mesos. I have tried elite bosses, but they are so annoying to find and to even get maplestory2 items

I also just made a maplestory Hayato
I made a Hayato, and people tell me it is an awful maplestory class. I really like the maplestory abilities. They said it doesn't do good damage, and it seems fine

Maplestory2 Magician Build help
Once you put AP into a stat, you cannot get it back unless you have an AP reset scroll but you'll need to buy it from the 10th Anniversary Coin Shop costing 160 coins.

Maplestory Couple suggestions on how to improve bossing and party play in GMS
What could be some of the biggest improvements to GMS in my opinion.I like the party quest house place. It was always really annoying to have to walk to a PQ to simply find no one else there

Slow down bot creation with phone verification
Almost all of the problems that GMS has can be traced, either directly, or indirectly to two things. Bots, and people taking advantage of events
