@Minininho02 It would be only waste of time if it doesn't give you any bonus or Prestige item/weapons being a thing but Prestige does have bonus and it's 20+ hp per Prestige, Golden skin crates rewards per prestige number and 10% Cash/Exp per Prestige but there's no Prestige items/weapons yet but i believe they will be a thing on the future.
Also nobody forces you to Prestige on any games that has it, it's the Player's choice.
@Mariobros188 grind until get prestige 15 seems boring and crap to me. the +20 hp bonus can make the rounds less challenge full since you will resist more to damage and have a less chance of die. the +10% exp can be useless if you're 60 and you dont want to prestige again. and the +10% cash can also be useless if you got already got all the current ingame guns. (except if you're farming to get specific number of cash)
