I completely agree with the fact that Gold armor is USELESS.
Here's why:
Doing a Finisher move is very dangerous and requires you to be in a safe spot right in front of your opponent. Also, chances are if you have a Gold armor, your enemy most likely has a purple one. So why would I spend 5 seconds doing the finisher move if I can spend less time shooting the guy down and taking his full purple armor while being in control of my movements during all of that time?!
The gold armor's passive ability needs to be completely changed. In hundreds of hours of plays, I never found a reason to use it.
