I'm not sure I'm quite ready to join a clan yet, but does anyone have a particular YouTube or Twitch Streamer I can watch that has a good introduction/training series on Warframe? I'm new and wouldn't mind watching some vidoes that give some good ins-&-outs/do's-&-don'ts.
Mogamu on youtube, then probably check his recommended channels on his page and the related channels section.
Some other people would be Tactical Potato, Brozime, AGayGuyPlays and DKDiamantes.
On twitch the list is probably similar, just check the most watched I guess. I'd say Warframe doesn't lend itself well to being streamed so there aren't that many large streamers covering it.
