For what it's worth...
(And just as a disclaimer, though I'm basically just a console gamer now, I still actually consider myself a PC gamer, and I basically grew up through the 90s/00s as a hardcore PC gamer, and usually still use it as the 'standard' for user interface...) (I add this to avoid my post being taken either as too pro- any platform.)
The couple times I did try Destiny -- and I had lots of fun, don't get me wrong -- on PS4, I couldn't help but quit because I felt like there's no way I could put MMO esque hours into a game that I felt deserved to be played with a mouse.
Again, totally cool as a console game -- I play games exclusively on consoles this days, almost for 4-5 years. So I'm very pro consoles lol. But the only way I personally could play Destiny would be on PC.
