Classic pvp community will never be healthy.
They thrive on sitting on lvl 60 characters and ganking lvl 20’s in leveling zones for hours at a time. Roaming around in large groups ganking solo players.
People that care about healthy PvP are playing games with actual rated PvP modes and devs that attempt to balance and tune.
There is a reason modern wow added resilience, PvP power, PvP scaled ilvls gear, completely separate tuning for abilities in pve vs PvP content, rated game modes, and war mode for the open world. Classic still has cc chains that can last over a minute, fears that don’t break to damage, and no PvP balancing at all.
