Edit: People are suggesting decreasing the amount of hp that you get per boost. I still think that giving people more hp than others is unfair and leaves players in a disadvantage when it comes to playing. Also, unless the hp boost is 2 or less, the hp boosts will still be op as they slowly add up.
Im mostly talking about the hp boost, everything else seems fine. It seems to be pretty unfair to give high rank players more hp, as it will make playing as a zombie annoying. Your attacks won't be effective or satisfying anymore. Having an hr with extreme amounts of hp in a server will just make a round take longer with not much to do to change it. On pvp gamemodes, extreme hrs will crush anyone else who just wants to play the game normally. Playing as a survivor won't be as fun anymore, as there is no real challenge due to your insane amount of hp. If this system is implemented, ill probably not grind prestige, as it will only make the game easier and less engaging.
20hp doesn't seem like a lot, but this is r2da, and the r2da community can and will grind it until they have the most hp that they can. Im always surprised at how much time people spend in this game, and now those people will be given game breaking amount of health.
I really hope pr reconsiders the current prestige system.
