Cool...what I like most about it is the fact you can go at your own pace. There is no rush to get something done before a weekly reset. Also, if there is something you want, the location is listed on the wikia. you can farm it until you get it. A heck of a lot of content....I can't tell you which I love more. Warframe or Destiny....They are equally good and bad. I say this...if Destiny had survival mode...Destiny would reign supreme. Defense and Survival modes on Warframe are hella fun.
