Honestly, the Prestige system in general was a bad way to encourage players already at max rank to keep playing. No, a terrible way.
No one wants to level up 60 times, AGAIN.
The Golden skins are only cosmetic, and they've become super common as well. They don't have that same exclusivity that they once had when only certain people could use them. They're worthless.
The bonus HP is very poorly thought out, and completely overpowers you as a player, granted you're a high enough prestige.
It's incredibly difficult to tell you get bonus experience per prestige, because it's so meaningless of a change.
The "hefty retirement fund" is definitely garbage unless you had millions of gold before you prestige.
The bonus gold really doesn't make much of a difference, since it's already so easy to grind a lot of gold. And once you have most, if not all, of the weapons, you'll just start getting an excess of it.
