Targeting.

[BreathlessTao]

What aethereal barriers are you talking about? Dungeons have walls and floors and other objects which prevent you from seeing enemies beyond theme on screen. Thus you can not target them. Adjust your camera so enemies no longer appear on screen if you can.

Uh-huh, go do Tam-Tara NM for example (mostly for the barrier, the mob just before the last boss). Or Sastasha NM for haywire targeting (the area before the first boss) or even Neverreap. Just the two most prominent examples.

Yes, the camera can be adjusted... I mean it's totally not an added inconvenience when you can't even see which direction you're facing in the middle of a mob while having to position attacks and at the same time also dodge AOEs and make sure nobody's getting anything they're not supposed to (aggro, debuffs, etc)... all that on top of perpetual lag which can very easily ensure you're just that fragment of a moment late with an action so whatever bad was about to happen - does happen.
Instead of, y'know, having a proper targeting system that doesn't cycle to mobs halfway across the map or to mobs out of range at all, or that simply defaults to cycling through the current enemy list (at least, if not actually turning the character to face those too) when you already have multiple enemies attacking you.
Sorry if I'm being very specific, but just tried to pick up WAR again and to me, these additional details really make it maddening. But yeah, the targeting system as a whole could do with these facelifts, regardless of my personal issues.
