Absolutely terrible item drop rate. The game forces you to buy everything on a third-party resource, for absolutely inadequate amounts of game currency.
Terrible attitude of developers towards newcomers. Get ready! When buying a game, get ready to spend the same amount on leveling up your character. The entire gameplay boils down to purchasing items from "Diablo Trade", since it is impossible to get anything through the game.
P.S. Even after paying huge sums for upgrades, games and dlc, next season everything needs to start all over again.
P.S.S. Blizzard remove third party trade!
