I dunno about doing the FTP model well. Getting anything in warfare takes absolutely forever if you're a free player. If you want to get a new suits (i.e. class), you need to grind for the individual blueprints (which means killing the same boss over and over again) then you need to craft the pieces, which means grinning for the material and then waiting a certain number real life day for it to be crafted (iirc you can only craft one thing at a time) and then you need to combine all the piece for a few more days and then you'll have your new suits... With all of it's power at level 1 making it almost unusable so you'll need to grind for that too.
In other word, everything is technically possible to be obtained if you don't spend money, but it takes forever so don't expect much progress as a free player.
I dunno if they changed it at some point, but you can definitely craft multiple things at a time.
There are a few multistage things like akimbo guns and combo stuff like the shotgun sword, and most notably, Warframes. In that case its 8 hours for the 3 components and 72 for the final frame (and a couple of frames are obnoxious and built out of other frame parts or multiple sets).
Forma is (as the above guy mentioned), the main obnoxious thing. Its used for making a variety of weapons, customizing your frame, literally everything including basic hallways in the clan HQ (which you need to access some weapons and frames) and here there for your faction levelups and other things, but takes 12 hours, and you can't multiqueue it.
I wouldn't credit them with too much altruism of course. There's stuff like only have part of the basic colour pallette in the freebie list (Black, always a favorite is notably missing). Several cash packs that even their community calls "Noob traps". A total absence of even a trickle of platinum (which will you need at least a handful of Warframe slots as there's a few that you can't dismantle without losing them permanently within the free-space.
