What is the difference between Crouch and Take Cover. Doesn't both Crouch and Take Cover either drop you into the shield cover or move you behind real cover?
Take Cover either drops your shield where your standing, or rolls you into cover (if you are facing one of those green siloutettes). Crouch just drops your shield where your standing.
If you use Crouch behind cover, you will still get the benefit from being behind cover.
The main reason i switched to Crouch was because Take Cover kept making me roll into cover too close to enemies, causing them to aggro on me. IMO Crouch is just more reliable.
