Balancing issues in PVP

[Valence]

DR is diminishing returns where effects are weaker in repeated uses. Use sleep repeatedly on a mob in pve and you will see the sleep timer get shorter till the point where the mob resists it. PvP used ro have this feature, but they opted not to use it in the new pvp.

I know how it works in pve, and no, pvp never had that feature. What PvP had was a binary immunity of 10s after you suffered a specific cc, for example stun: you were stun immune for 10s, but not heavy immune for 10s. It's exactly what cleansed purify does right now, but it was only for one specific type of cc, and twice longer. And a nightmare to keep track of.
