On the subject of pay to win... [spoiler]Tldr: Pay to win =/= Pay for convinecd [/spoiler] The way item unlocks works is you have to level up your player master to unlock new weapons, this apples to paying cash from them. You gain mastery from doing missions and levelling up weapons, Warframes and companions. If we are both the same mastery level, there is [i]nothing[/i] in this game that you can buy that I can't build. And on platinum, it can be uptained in game semi-easily if RNJesus loves you. Most players use platinum as currency and you can earn them by selling stuff that drops for you. You can also get som from logging in. The only thing that I can't get with platinum is cosmetics.
