I think that nerfs are fine.
I just wish they would be pointed at some of the more obscure, but terrifyingly broken, spells, or even some of the "golden cow" spells, like similacrum or clone.
I really don't get why lore warden needed a nerf.
It was great at what it did, for sure.
But by definition, there will always be a best at something, and nerfing the best at an option that, while nice, doesn't work on a lot of things due to the existance of freedom of movements, monsters without weapons to disarm, and anything thst can fly, the tricks of the lore warden were only so effective.
They could still deal respectable damage, though, making them respectably versatile.
As a melee combatant.
But if the old archtype is banned, it makes that all go away- back to DPS only melee builds for fighters.
