At current, whomever starts highest wins due to advantage spam, which means that you can trivialize encounters by approaching them from the highest elevation possible. Those that force you into set positions are simply unfair.
^So this is core rules btw. So you complain about core rules DnD being dumb and agree with me - perfect - i agree. Core rules are dumb. Get on the hill win game.
Height advantage is not a core rule. This just shows that you probably have no real clue about the core 5e rules tbh. Yes a DM *could* give advantage for height, but a DM can do that for anything at any time. You are very hostile in your tone, but fail to back that up with facts. Very unpleasant behavior.
