Actively working to deprive enemies of high ground when they have it because you feel you must in order to be effective IS being forced to work with the mechanic even if you hate the fact of it. By talking about all the things you could do, and suggesting that lots of people do them regardless of their feelings on the matter, you're proving the point that others are making, Rag.
If you're struggling to imagine that a large percentage of players will play the game, and want to do so effectively and without hampering their chances, and so make full use the over-bearing homebrew mechanics because they are the surest and most effective way to do things... even if they have a strong distaste or even dislike and disgust at the design... then I'd hazard to suggest that that is a failure of your imagination, and of your understanding of human beings in general. If you can't see that players are forced, by and large, to benefit from and be hampered by these mechanics, regardless of their feelings about the homebrew, simply while playing the game - even if they ignore it as a rule - well, few others are having trouble understanding that, so it sounds like the difficulty is on your end.
If you can't see that Larian taking from that play data and saying "We see that most people do try to get advantage from high ground when it's easily available, most of the time, and they also try to deprive enemies of high ground when they can do so: that must mean that people love using our high ground mechanic!", is a big problem for their reading of analytics, then again, the missing link of understanding is on your end. It is a problem, for several very pertinent reasons that have, at this stage, been explained, at length, many times on these very forums.
