Yeah, I understand your concern with other players, but in my experience, Warframe player-base is nontoxic when it comes to missions. You rarely see people talking. Most people just rush through the map and if they are a really high MR, they clean everything is seconds and you just gotta make your way to the exit xd
I will start downloading warframe today and see how it runs on my laptop (if it can even run it with a playable fps rate). I will keep you updated. I just hope I wasn't kicked from my clan xd
