One of the isues with destiny was selecting ammo synthesis from the inventory while playing in activities such as strikes, public events and specially the raid. Many of my friends including my self would have to find a place to hide in order to use the heavy ammo synthesis from the inventory, but sometimes an enemy would kill us. It would help if D2 had a button for selecting ammo, without going to the inventory. Emotes needs an quickaccess menu something like the division, an overwatch use. Being able to carry more emotes or all of them. It was somewhat annoying selecting emotes in Destiny, because i would have to go to the tower, then erase an emote to make space for the new one. It felt limited. The destiny app slightly fixed the problem, but it would only work if you had the emotes in the vault.
