Okay so gold armor is a bit OP compared to the other legendary items. I do not suggest removing it, but changing it.
First it heals way too fast and is a complete game changer in a lot of fights. Self rez makes an obnoxious noise and you can get killed easily while doing it. Helmet is good, but not OP and is not like an instant charge rate. There is no weaknesses with gold armor.
I suggest that maybe when you finish someone it works like a phoenix. Full health and armor (some vulnerability). That or just give it one extra tick over the purple armor. Right now its stupid how fast you can heal.. Even all the pro's say it is op.
That or make the fast heal comparison to lifelines and then she can get the faster heal since its her passive.
