This^. I agree that the player should never be penalized for being creative with an encounter as long as it isn't an exploit. And, I'm pretty sure I'm right about this but correct me if I'm wrong, using the terrain to your advantage has NEVER been an exploit. The soft kill zone shouldn't have been implemented. Your suggestions to change enemy ability/AI to counter people from sitting up there the whole time is right on point. Kudos, OP.
