Chem launcher - You shouldn't have to wait for the charges to come back if you are out of combat or haven't used them.

Turret - Weather effects it, it tracks the enemy with it's red laser but won't shoot if it's foggy or raining WHY? Yet you can send the Drone far across the screen and have it track and attack enemies in the same weather.

Turret & Drone - Locks onto 1 enemy and will not let you change targets manually, unless you destroy it and redeploy.

Restorer Hive - Should only send charges to players, not to any skills (it's a waste) that's what the Artificer is for.

In-Game Text - Should be enabled by default. Some people would rather type and new players don't know about it until someone tells them how to turn it on and use it.

Damage numbers in a list (like PC in the chat box) - There's no reason why console players shouldn't have this option.

Move/Resize UI Elements - Currently can't move/resize HUD (ammo/health/armor section). Give more options.

Shooting Range Revamp - Make it more useful and work correctly.

Shields - Should not be effected by special ammo from NPCs if hitting the shield. If the bullets hit the body, then yes you should be effected.

FX Mod Slots - They have been in the game since launch and even with the Ultimate Edition there are like 3 skill FX mods that cannot be obtained.

Revamp Unpopular Skills - Example: no one ever uses the Remote Pulse.

Skill Mods - Change/Add and include a description what it does and what skill it's for. Some mods don't do anything useful for certain Skills.

Mods (Skill/Gear mods) - Show a symbol in the loot beam if it's max roll mod, so you can see before even picking up to inspect.

Loot Sharing - When walking up to loot give the option to share without first having to pick it up then share.

There are many more ideas, but these are the ones that I can think of right now.
