As of right now, purple down shields are the only ones worth a shit cause all it takes for the other shields is literally a second and its gone.

Knockdown shields are supposed o discourage thirsting, and ONLY the purple shield is one that takes any amoumt of time for your team to take advantage of.

Grey knockdown shield is 100 hp and should be 250.

Blue knockdown shield is 250 and should be 500

Purple knockdown shields should stay 750.

This makes upgrades more on track and makes them worth a shit.

I literally find myself after downing an enemy, rather than reload spend the rest of my mag thirsting the guy because it takes absolutely zero time and prevents any possbility of revive. Grey and blue shields may as well not exist.
