What are some QoL improvements you loved in previous Treyarch Zombies and which QoL changes would you do for a better CoD Zombies in 2020?

Let me start with a couple from Bo4, even though it had a rough start *cough* bluescreens, the game had some big QoL improvements.

For example:

- Carpenter fixes your shield

- Max Ammo replenishes full weapon ammo

- Easter Egg progression feedback ingame

- newly added multiplayer weapons added to zombies

*What they should implement:*

- not removing Double Tap

- newly added multiplayer weapons fully customisable without unlocking the gun in the gunsmith

- less special zombies, looking at you Chaos maps and AO

- pointsystem like Bo3

- last zombie shouldn't die out

- new Wonder weapons
