At the moment, bots seem to conduct a monopoly on blank slates in game and offer them to get 30m MaplestoryM Mesos a bit. I would love to find the limitation in the reward store upped to 5 or so a month, or possess clean slates drop a great deal more frequently (perhaps from zak, hilla, etc) to get down them to 5-10m a bit.
Untradable gear - largely Android hubs, but also sweetwater equipment, etc.. As someone who makes most of my cash off of hearts and sweetwater, I would rather be broke and find something else to sell and be able to trade these around my maplestory2 account. Even being able to sharing tag these items would be better than nothing.
I understand GMS is limited to what it could do, but Spell Traces need to be updated to reflect what regular scrolls can perform. I do not mind weapons being stuck in 9, so that they can earn money off Primes with Marvel, but Android hearts should also be in a position to have 9 attack! This wouldn't hurt the Prime marketplace, as min/maxers would still need them. As somebody who is probably considered mid class/mid game... These are the largest glaring defects to me.
I've played maple for a while, but still don't understand the perfect way to produce billions of maplestory2 mesos. I've tried elite supervisors, but they are so annoying to find and to even acquire maplestory2 items. I need more harm on my wind archer, my damage range is 78000-90000 (level 153}. What's so gosh darn costly and I cant fund my characters values crap.
I don't spend money on maplestory2 MS and am considered underfunded, but I get around it. There are a number of really wonderful MS players out there which will help you too. I tend to NPC most stuff because of hating the free sector. Just look for a few people around and speak to them.
