The lack of variety in weapon use. Nothing but shotguns and hand Cannons and fusion rifles. The way the weapons are balanced and the maps cater to only one type of game style/strategy. I'm used to halo multiplayer where you could literally pick up 90% of guns and use them if you were skilled. You see a lot more weapon variety in halo than destiny, simply because the guns and maps are balanced well and people don't need to rely on just one style to get kills. Supers in my opinion also -blam!- up everything especially when people use them as a crutch instead of as offensive weapon.
