When Crota hard released and those that were able to complete it, really felt special when you got that Glowhoo and showing it off. They should do an PVE content similar to Iron Banner where it comes once a month and it drops an exotic/legendary item specific to that encounter. On that note: Where's my Queen's missions!
YES! That first hard kill was so SATISFYING. After beating our heads against the wall for hours, nothing felt better than killing that fuck. Best "Destiny feeling" to date in my opinion.
I would say wow is pretty much only for hard core gamers tho. No casual 12 year old "gamer" is playing wow. (Iv never played wow, so i might be way off )
Destiny went with the COD formula.
I never played WoW either, but definitely know it's not only for the hard core. A ton of casuals play as well.
