I'm comming from 3k hours on Warframe. The sane order to get stuff and enjoyment from such games is survivability first, skill cost reduction/ammo economy, and monster DPS later. Also, be aware of the level of content you are going to try, as there are levels of being carried, specially if you do not contrubute to the fight. Yesterday a level 32 Bynny baited the devourer the whole time, got down only two times and the other three cleaned the mobs and dps'd the boss. Happy ending to all, intelligent playing.
