To be fair it is a valid complaint. Got GOW2018 when it came to PC and was appaled when I saw that the high difficulty setting was just dog shit and all it did was adjust the stats to the point where a basic enemy took several minutes of whacking to kill. I don't call it artificial difficulty, just bad design. Stat increases are valid but only to an extent. Addind a bunch of hp to enemies does jot make the game more difficult it makes it more tedious.

Increasing their damage is fine, but instead of adding a ton of hp it's better if enemies become more aggressive, tightening the parry (if mechanic exists) window, adding more enemies or enemies with some status effect etc. Making the player spend 20 mintes in a fight instead of 5 by HP and damage changes does not equate to difficulty
