Every exotic we saw in the new trailer looks like an actual exotic instead of just some
"Every kill makes your helmet bigger"

I still think the majority of the clips are exaggerated a bit and we won't see some of the chain damage kills from the bow or malfeasance. I also think the titan reflect boots will be gimmicky and probably only yield reflects, rather than kills. The trace rifle probably won't kill anything more than thrall at end game, or it will be very limited ammo. The sword projectile will probably be weak like in d1, and the hunter dodge won't replace wormhusk crown, so it's already irrelevant. If ace of spades doesn't have a higher damage variant of kill clip, I don't see it dominating anyone's exotic slot. The warlock chest piece giving explosive elemental rounds on kinetic weapons sounds promising, but we'll have to see if they are element locked. The two tailed fox launcher is debatable depending on if both rockets damage output is split or doubled and what the ammo count is like.
It's happened before; hype trailer is meant to build hype, but the gameplay probably won't be delivered during significant content runs.
