Not exactly a normal MMO. Playing MMO's like ESO is basically centered around continuing a story for a long time and getting gear after each level to continue onto the story. Destiny has been basically built around the weapons and armor, and to get those we have to grind and search for countless hours to get them. Not to continue onto the story where the level before our armor set isn't continuously being thrown out without much thought. Even Bungie said one of the biggest reasons people put in the countless hours is because of the weapon collecting and they want us to continue using our favorite weapons. With a game where one of the biggest design features and main addiction is in the weapons we collect, then yeah, it would be horrible to have it all go down the drain.
