Here's a little of my observation/opinion on why AQ3D isn't receiving the popularity it's supposed to receive:
The game right now is truthfully stale and boring. The combat is literally the same as AQW even though they proclaimed an entirely different & new system of combat. To make matters worse, they came up with the really horrid idea of having that "Class Daily Token" system for every upcoming class to come. Not a single sane soul liked it when they had applied it to Cryomancer & Blaze Blinder in AQW so I don't see why they went through with this. I suppose it's to go with their poor attempt at mimicking Warframe's crafting system (in Warframe it makes sense, but unnecessarily locking people out of their crafted gear for 12/24h doesn't belong in a game like AQ3D). Yeah, just my take on why the player count is lower than DragonFable's. (DragonFable in the day is 200+ players online, AQ3D around 180~ players online)
