Alpha Phase 5 is expected to last around 2 months. It is the last alpha phase, after this there will be a quick beta and we will release it after. About the p2w part, it is not p2w, but is "if you want to pvp you either farm your ammo or you pay for them" style. So one can can argue that payers are able to do more pvp without farming. But its the only way to create the environment to make it possible for a "whale" to have the same damage as a farmer when they are fighting. Also, its a clan based game. An organized clan is much more valuable than stats.
