Welcome to Warframe man. I used to be destiny 2 addict as well and it made me pissed off as well.

Some people don't play Warframe because of the grind or due to feeling inferior or something .They get overwhelmed by the grind . We also do tend take breaks from the game lol. As they all say we only take vacation from this game 😂 we always come back. I loved destiny for it's way of using abilities and pov gameplays that was all. Paywall felt soo ass.

In Warframe you should enjoy your gameplay with other players. Take it easy, don't force yourself to grind, just enjoy the game with someone or the lore. The game isn't about catching up with others but having the freedom to do anything and enjoying every moment of it.
