I don't know if it's buggy terrain, but there have been way too many times where I'm up on a ledge and somehow can't see anything beyond a couple feet from me (not blinded, I checked :P) . Or there's clearly a LoS to my target and I can't hit them. Which is totally ok IMO - terrain can be a wonky beast to tackle, but a pre-view like this would let me judge that. Sort of like ... when you're trying to teleport or netherswap someone. And they're in range and lit up but you get a red X when you try to drop them somewhere - no big deal, but it didn't cost me a move or AP just because of some UI bug. I can just drop them somewhere else or cancel out of it.
