Quarterstaff Storm Wave interrupted by terrain elevation changes on Atlas Maps

I'm playing a Monk and now that I am in Atlas end-game I have noticed many of the maps have super bugged terrain where different elevations are causing Storm Wave to halt literally in front of my character and often results in getting killed because my attack that should have one shot half the screen didn't hit any enemies. Also certain pots, rocks and other stuff seem to completely nullify Storm Wave as well instead of Storm Wave destroying them.

As a side note, I have a suspicion that part of the reason why the Atlas maps are so laggy and crash the client is because you guys have a ton of invisible artifacts on the maps related to elevation that are noticeable only if using skills like Storm Wave, but that the client still has to load.
