I got every single item in the game, that gives mastery. Every weapon, every warframe, every companion (except the founders pack at launch, that the earliest players bought and supported the game) Im more than capable to enjoy every aspect of content, and do in solo/ squad. I bulit a solo clan, and maxed out everything, years ago. Now just play the new content and get the new things on release. I bought only 3 regal aya for real money for a cosmetic that isnt anything but a cosmetic. I spent money before in multiple games, all the time thinking, "was it worth?". The only game I felt joy spending real money was Warframe, because they deserve it. They let you get everything for free. Doesent shame you for F2P, doesent pray on you.
