At least you gave it a shot (which is more than I can say for many of the Destiny folks around here tap tap tap)
And yes, make no mistake, Warframe is a very grindy game. If you're not into the grind for gear - than Warframe probably won't hold your interest. However, having said that - if you don't mind the grind, the game will reward you for your patience - planets are marked with what resources they carry (and at what level of rarity), and most bosses contain the blueprints for a specific frame. Most of those bosses have taken me around 10 - 12 runs to get all the blueprints I needed. For what its worth, I'm now 2 pieces away from farming the entirety of the prime vault which was unsealed for about a month including Rhino and Mag Prime (frames), and the weapons Boltor, Boar, Darka, and the fist weapons - so once you know how to relic farm (in addition to using Sydicate points) - it's very do-able. During those runs I'm also now finishing construction of Oberon and Banshee prime (already had Nekros and Trinity).
So grindy - Yes, very (I nor the game make any bones about it)
Will your grinding pay off - also yes.
As a disclaimer - I have spent about $40 on the "free to play" game thus far, but considering the time I've invested, I A) don't mind supporting the game and B) have spent 99% of that platinum on inventory slots (hear that Destiny players - you want more vault space, you CAN HAVE IT) and a few cosmetic items because dammit, I wanted them :)
