A small change that would be great for DKs is if Glacial Advance (particularly the one that procs from Obliterate) and Frostwyrm’s Fury didn’t go through walls and similar terrain in M+. I cannot tell you how many times I’ve accidentally pulled extra packs in keys because my uncontrollable/proc’d GA fired off into Narnia through terrain.
It’s even bigger issue with Frostwyrm’s Fury. For example, in Dawnbreaker, I find it hard to find places in the town (with its density) where it’s safe to use. You can pull mobs on the backside of the house and on the street when fighting the lieutenant add at the Steelstrike house. If we knew that using it against terrain like a wall or house would only hit the mobs between our character and that terrain we would feel a lot safer about using it more frequently.
