PK rewards in 300k increments is extremely step... I suggested the rewards not specifically to reward people who already PK and spar, but to make it more active and to encourage people to do it more
Someone who has never PKed before would look at the first reward tier at 300k and assume they'll never get it and just not be interested at all

If they make it in increments of 10k and 100k, up to like 100k and 1m, I don't see how that doesn't provide enough longevity and incentive for the reward system, considering it's been 6 years now and no one has achieved either
