Are you testing a change to the change you just made? Alternatively, maybe the change was just bad. Balance is one thing, but I don't know a single player who isn't annoyed by wonky LoS checks; that is why we loved Dante so much.
The game itself is more fun when we bump up against an inconsistent system like WF LoS less often. Exposing us to it further by adding it to a frame we already loved is... a move. So now, to play Dante, I get reminded intermittently that LoS works badly. That impacts more than my experience of just the frame.
