Npc ai

You aggro an NPC, or an NPC aggroes on their own towards you and they are a caster, moving behind walls/out of their line of sight does -not- make them run to you. Like they should have.
Instead, they stand still and get stuck on a casting animation, like they get bugged. Won't move to you/to a position closest within LoS, won't reset. They just freeze there in the middle of casting their thing.
Obviously, this means you can't pull, you can't "separate" mob groups and you surely die like crazy in the high level areas.

Have had this multiple times, in various level ranges. Definitely a general issue with all caster NPCs.

As you surely remember yourselves, in vanilla LoS had a huge importance in gameplay. It's a big issue with this. Results in so many solo quests, group quests, and surely instances being proper overkill difficulty-wise.
