Gunplay goes a bit hand in hand with combat interactions between AI and the player. Controls do not have to be silky smooth to create great gameplay. They just need to be good enough. My opinion, the interactions with enemies are more important and lead to a more immersive and fun gameplay. Ive done entire threads on how to improve AI in this "grindy" game through ability and weapon tables, movesets, and interactions between the enemy. Take Halo for example. The grunts were awesome. They taunted, they threw bunch of grenades when you were behind cover, they ran in fear when their Elite died, they used varying weapons and ability kits, they would whip out grenades and go all kamikaze on you....their combat interactions were great. Destiny needs this badly for its gameplay. To me, Destiny as a whole--minus TTK--feels like an incomplete game.
