Let me just clarify on the grind. Destiny has weekly gates on everything worth grinding. Raids, high level PoE, Trials now, Weeklys, etc. You play, turn it off, wait til next week because you've done all you can do.That's just not true. Yes it is a Grindy game (and Destiny isn't???) but unlike destiny you can actively target what you're grinding for, and what planets to farm the material from to get the weapons/warframes you need. Destiny you put in the same if not even more of a grind for even less of a chance to get something useful. 50 hours into the game I'm on my 3rd warframe and have been crafting so many weapons I am out of inventory slots to make more. Without spending a cent, spending money in warframe is mostly only for cosmetic additions. Any weapon and frame can be crafted with a reasonable grind for free since you can target what planets will drop the pieces you need. Compare that tot he RNG shytstorm of destiny
Warframe. You're getting PSO lootdrops. Yes, you know exactly where to get certain drops, but that doesn't mean that is in any way easier to get. You can be running a survival mission dozens of times for a fukking blueprint. NOT THE WEAPON. NOT THE PART. THE fukkING BLUEPRINT. God help you if you're trying to make a dual-wield.
And don't make me get started on the Tower/void shyt you and I both know that the mid and late game stuff in warframe is nothing anyone wants to talk about
So its just a matter of what you're able to deal with better. Honestly, I feel the gameplay for Destiny shyts all over Warframe and thats my main reason for sticking to Destiny right now (taking a break because the grind demands it). But you can outright buy most stuff in Destiny
