My only wish - For monsters to be able to drop gold! That's the most important one! Another reason why a lot of people stop playing wonderland is because they can't get enough gold to support themselves and thus, getting confused by tutorials or explanations from high lvl people and deciding that the game is too hard and pointless. Example of a good game with money drop from monsters: MAPLESTORY!!!!! That's a good game that everyone likes because not only does it have everything explained to you but it also has mesos dropped by killing the monsters. Why can't they just make monsters drop gold in wonderland? Newbies in wlo always buy eqs from ship voucher places and sell them at super high prices and think they're gonna get rich soon. It's impossible if only newbies want to buy it but they don't have enough gold and the people that do have gold are usually high lvl people who know not to buy that stuff. So what's the point in selling if it takes forever for people to buy? People see something they like and are willing to sell everything they have to get it. If they don't get the money fast enough, other players will buy it or the person will pull their stall and you won't get it until you see that person sells that item again. If monsters were able to drop gold I imagine it would be something like this:(and of course igg would make it little gold so you play more)(btw: this is the add up of an entire battle of that lvl of monsters)
LV1-20: 5-15 gold
LV21-40: 20-35 gold
LV41-60: 40-65 gold
LV61-80: 75-90 gold
LV81-100: 100-115 gold
LV101-120: 125-140 gold
LV121-140: 150-165 gold
LV141-150: 175-200 gold
LV150+: 250 gold

That's just my wish though. I saw that it was mentioned at the very top but no one bothered to care about it so I wanted to mention it down here.
