Mystic Coin scarcity is a big problem for the Gw2 Community atm in my opinion. I understand it is a free market but Mystic Coin's supply and demand gap is getting bigger every day. There are only a few ways to get Mystic Coin per day such as Ley-Line (1 coin/day), Fractal Challenge Mode (avg 2-3 coin/day -RNG), Monthly Login Reward (20 coin/day), and WvW (6 coin/ week if you finish all the rewards).
For Legendary Gen 1, you need around 231 Coins for 77 Mystic Clovers, and for Legendary Gen 2, you might need at least 481 Coins for Mystic Tribute. So if you do everything you can get around 5-6 Coins per day and even with a static team for CM fractal you need to spend at least 1 hour just for Fractal, it will take at least 1-2 days to finish WvW track if you dedicate all your game time to WvW - 1 day if you get lucky with Outnumberred all days, for Ley-Line you might have to do it right after reset otherwise you can't because not many people do it these days. All that for 5-6 coins per day, in my opinion, this is stupid, and not to mention if you grind your balls out for gold to buy coin it will also hard to get the coins at a good price since there are bots on the TP market and not to mention those TP Baron who controls the coin market as well.
Take Casiano/Goldrim for an example, he has 10 million gold worth of coins, and right now he is keeping it to drain the Coin's market and push the price to 4 gold. There is nothing wrong with it if you are economy players or hardcore players, but if you play the game casually it is just so hard for you to craft just 1 single legendary. Right now, the demand is huge but the supply is very limited because not many Gw2 run CMs Fractal and Ley-line Daily. Not to mention, there are so many afkers and bots in WvW, you can see a lot of people around in WvW maps but most of them are doing wall running or afk just for Weekly Reward, it kills WvW, to be honest. EOD expansion and Steam release will be here soon and demand will rise big time, supply will also rise but the supply changes will not be that much anyway.
Here is my suggestion:
-Bring back the Mystic Coin Reward for Daily as we had years ago - 2 Coins per day, it will be enough ( Still need at least 89-90 days for someone who only login and do dailies to craft Gen 1 and at least 150-163 days for Gen 2). It will not break the Coin market, the price will stay around 1g50 - 2g most of the time. It might boost Anet Sale too, there will be a ton of people will buy alt account just for 20 coins per month and 2 coins per day.
-Anet needs to have a bit of control of Gw2 Marketplace to avoid inflation. The coin is reaching 3 gold at this moment and who knows how further it can rise. Remember when coin price was 15-20 silver per piece and not is might get to 4-5 gold, how crazy is that.
Those things above are just my opinion and suggestion. Let's me know about yours in the comment section below and thank you for reading and replying
