Not to mention that often, people only play either part, like either the story or multiplayer (or warzone for that matter) without touching the others.

How to only install warzone and get all of your classes 1. You will need to make a new blizzard account. 2. Log into your Activation account on their website and unlink your Blizzard account, and link it to your new account. 3. Uninstall call of duty and install it on the new account, and now it will only download warzone and you will still have all of your classes.

If you want to play multiplayer then you need to play on your main account (and install CoD multiplayer ), but you won't have all of your classes.
