This is all starting to reek of people who think they are good at games because they look up guides online and save scum, you aren't special and ruining the game for yourself is your problem not Larians.
First, to repeat, the game is too easy on the hardest difficulty. This is not because of "OP" builds. I can take any straight class with any three companions and walk over everything in Act 2 and 3. The hardest difficulty should be fine tuned where that's not the case.
Second, no one is advocating for removing lower difficulty levels or even removing what is currently labeled tactician.
Third, you are being rude. You are making personal attacks. Why? Is that necessary? Is that helpful?
--I'm not aware of anyone here calling themselves special. Why are you going out of your way to tell them they are not special? I get the impression that you're vicariously spitting venom at someone from your past. It's not appropriate.
