I think currently there is a lot of room for improvement when it comes to incentivizing prestiging. With the upcoming skin update I imagine It will feel like there is a little more to grind for, but I think there are more improvements that can be made to the system.
These are in order of what I would like to see most to least.
Per-prestige Stats
If you only implement one of the suggestions in this thread, please make it this one.
I would like to be able to see my stats for the current prestige only. Ideally this would be implemented by having a page in the stats menu for each prestige, and one page for overall stats. This gives a nice way to track progress, as apposed to the current system that doesn't allow stats to change as you get better almost at all.
Cosmetics
A few ideas for more cosmetics that are unlocked each prestige, rather than with number of kills. These ideas are focused on giving a subtle yet noticeable (to other players) way to show off your progress to other players in game. None of these should be too in-your-face, things that, if a relatively knowledgable player saw, they would get an idea of how much time/effort someone's spent in game.
- Unique bullet tracer color for every prestige.
- Unique smoke color for every prestige. Ideally not super bright neon colors, just colors of smoke that you could expect to see irl.
- More character cosmetics locked behind prestiges.
- OW-esque golden guns. Each prestige a player can pick a gun to unlock a special skin for. Whether it's actually golden or not doesn't matter, ideally the skin would be something that is a little more noticeable than the current red and green skins that are unlocked at 3.5k kills.
