I don't play on this world, but saw this thread and felt this needed to be said.
You don't need to spend money to use premium benefits. In that sense, it is a tactic and skill in and of itself, like any other element of the game.
Some accounts join worlds purely to make premium by farming, selling resources and repeating the pattern. Then, that premium is used to fund them in the next world. Even when you are spending premium on a world, you can make it back after a certain point and keep building more premium points to your account whilst still reducing costs of building by 20% and speeding up buildings.
Premium isn't a pay-to-win setup, except for the lazy. You can sell resources to fund a premium account, account manager, LA, speed up buildings, reduce cost of buildings...without spending a penny.
There is literally nothing to complain about
