Feldon Due to a bug which is robbing Raid mobs of their Crit Bonus, most of them have been permakilled on PvP servers until a bug fix can be rolled out. [EQ2 Forums]
UPDATE: You can read more about this issue in a thread started by Silius EQ2 Forums.
We have found the problem and will be hotfixing it as soon as we can. There is an issue on PVP servers causing NPCs to get 0 crit bonus benefit resulting in an unintended reduction in challenge. As a result of this discovery we will be permakilling all current content raid mobs on the PVP servers until the fix is patched to live.
We currently plan on pushing this fix live tomorrow along with some balance adjustments for the all servers. Once again we are sorry for the inconvenience.
