Play a non loot based FPS such as Halo5 and you'll find that there will always be favoured weapons. Destiny at its core is an FPS with RPG elements tacked on. Mida and 1kys simply represent that scout rifles and snipers are the best TTK currently. TLW just showes off that nerfing shotguns and extended TTKs have removed any counter for that gun. No matter how much balancing Bungie does you will ALWAYS have a handful of guns that are more popular than the rest. This why its fairly obvious Bungie doesn't understand balance as it applies to Destiny.
