Hello SEPHIR8TH, I understand your disappointment in not getting what you were hoping for. This seems to come back to the pay-to-win vs. time and dedication arguments in the game. If you give $40 to get strong, and everyone else does, then it just forces the mechanics behind the game to keep increasing stats, which implement new items, which people will pay for just to hit another pay-wall. The RNG negates this, it puts everyone on an equal level, and people who spend money just have more chances to be lucky but won't be automatically better for it.
I would say don't quit now my friend, the game is fresh, and if you enjoyed it enough to put money into it, at least give it a bit more time; remember the game is still only soft-launched for now. We need more people to create a strong community, and I'm sure these little irritations can be fixed with time.
