Warframe is far from perfect aswell tbh. Paywall for everything, long crafting times to passively force players into spending money (f2p mobile game 101) It has dull and lenghty unrewarding grinds, the games engine is ancient, the levels arent unique enough, same playstyle every single mission, ability spam build heavy while ppl rarely even use guns etc etc. Imo you are comparing the devil to the devil. One is looked at in a positive way by their community because they are used to the monetization heavy game structure, also just because almost no new players play and only hardcore ppl play who have already acquired everything -> Warframe. On the other hand theres a completely different community of players playing Destiny. We are not these harcore elitists who enjoy pulling out their credit card every other session. Most of us are casuals who enjoyed a looter shooter. Bungie catered to the hardcore elitist minority tho. Look how many players are left now that most ppl realized that. lol.
