Destiny is not a mmo, it's a shared-world shooter. I hope it was an mmo with open world galaxies, planets lots of enemies etc. As you said, it's easy to level up and fight and more of it doesn't make sense but our grind for enjoyment? I didn't enjoy much, do it for to upgrade something etc. For all mmo's each new dlc has more powerful weapons and that weapons will not do too much effect on your game play and character. Cause they are rpg and you just click to an enemy and you char do the rest. But Destiny is a FPS and weapons has direct effect to players game play experience.
