Spells: Getting problems with range when casting Lightning Strike

[greer]

I'm getting what feels like spurious "Your target is out of range, get closer!" errors when trying to use Lightning Strike.

I'm (attempting to) kite yetis in DL and I'll grab some, snare and bunch them up and cast and about 80% of the time I'll get "Your target is out of range, get closer!" - sometimes, even when they are on top of me.

I've tested that I'm not just targeting the wrong mob - I can still start a snare or single target nuke, but nope - not in range for Lightning Strike.

The nuke I'm using to test range is Firestrike, which says it has the same range (200) as Lightning Strike.

So this is something unique to trying to quad kite? That lag, or having multiple mobs near me is causing some kind of lag or delay?

Would love any ideas! Thanks!
