The main reason I don’t play HC is in the absence of haptics you have minimal feedback on weapon orientation at night &/or with a visor.
Not knowing where my hands are is not a problem I face when practicing swordsmanship IRL.
Now, I can see an argument for reducing the contrast/opacity a bit (in general), and for suppressing the parry icon… but the combat star (in some form) is necessary to provide even part of the awareness of position and cutting lines which come naturally as you move IRL.
The rest isn’t significantly different to how I routinely play (no fast travel, majority of saves by daily cycle), and the removal of much of the ‘high end’ loot from random stashes in the wilds is a definite improvement, which I may well mod into my standard mode play, along with even more economy rebalancing tweaks.
