WoW Classic – Rank Decay
Each week there is decay of your total amount of RP by 20%. This makes it impossible to reach high PVP ranks unless you are placed into high brackets because the decay will be greater or equal to the amount of RP you received.
The amount of RP you will have after each reset is thus: 0.8*RP (last week) + RP (this week)
Example: You have 40000 RP (=rank 10) and you are placed into bracket 10 (=9k RP) on reset day. After the reset you will have 41 000 RP (rank 10) : 40k*0.8 + 9k = 41k
