For all people who thinks that Warframe is Pay2Win: Try this... Start the game, start with Loki or Excalibur. Play the Warframes to level 30 (1-2 days). Farm for some basic weapon mods to improve your damage. Each mod has a special drop location. So you know where to farm and you can farm as long as you have fun, there is no weekly limit or reset. After this, buy Tonkor or Atomos in the Market (no real money needed). Farm for Forma Blueprints and Forma your weapons. After this you can stand most of the game. For those who never played Warframe it will sound mysterious but it should show proof you Warframe is no P2Win. For this you don't need real money.
