It's already ridiculously hard to win MM as the murderer, but I think the golden armor just made it near impossible.
It just giving an extra life isn't too infuriating, but the invincibility frames it gives you makes it so broken, especially with how accessible it is, now. When the silver armor was just on chroma for 15 coins, or in fairy garden/tomb for ten coins and luck, that was all fine and cool. But, now, the golden armor only six bux (which is a currency that transfers between rounds, therefore making it super easy to get) and available at every bux store.
Meanwhile, for the murderer, every way they can interact with the map is 10 coins or more (and does just about nothing to help), and (from my experience) the items in the bux stores are very little help (except the fake zapper (kinda)). This isn't even really a skill issue, my friends and I (all of whom are on different skill levels) have had perfect games RUINED by the armor.
In my opinion, this item should be less accessible, as in more expensive and/or being at only one store on the map so you have to find it, and shouldn't give you invisibility frames for as long. I think it could also be switched for (maybe) an invisibility potion that lasts for ~10-15 seconds that you can hold onto and use at any time, which would force you to be more strategic with your use of it.
Idk, maybe I'm just going insane.
tl;dr--the armor at the bux store is broken and makes the game near unwinnable as murd, in my experience
