Concern: Line of Sight Issues

[Doors]

Is healing through walls going to be addressed on red99? I was just reminded that it was possible on other boxes. I can't remember for sure if it was like this on classic. and I'm almost positive it existed on vztz. I know its possible on p99 but would like to see that changed for red99.

Healers glitching into terrain or unpassable terrain with a levitate brings back some memories. Also whats going to happen with casting ranges dealing with people who use levitate to get 2000 feet above someone and just cast on them? Is there going to be range values for that similar to the range values dealing with horizontal casting range values?
