Well I don't think Warframe is pay2win, it certainly helps but pretty much everything can be gotten without buying cash-shop stuff, just requires some effort.
Only downside to Warframe for me is the fact that everything that it crafted takes real-time to build, usually 12 - 24 hours for a weapons and 3 days for the warframe (+12 Hours for all 3 warframes pieces if you craft them all at once)
