Take him out of the game altogether !
Let people play in peace, why because of two pvp zones and four arenas that are not updated for years, everything is overgrown with moss, and only a couple of hundred people who decided to grow old and die there play, you constantly nerf and cut something, and then ordinary players suffer.
Either remove this pvp altogether, or separate it from the pve of the game thoroughly, make them their own armor sets and leave all the rest alone.
And stop touching necromancers because of your PVP , there is no strength from these bullying
