The clip, unfortunately, seems to confirm what I have been fearing since Tactician spotlght during PfH - the combat simply gets filled with Larian cheese, rather than cranking up difficulty. They should have called it a "Cheesemonger" mode, rather than a Tactician.
I encourage not taking the clip as a representation of the Tactician difficulty, because it's truly not. I just wished to showcase how this shoving cancer is present in Grymforge even on Tactician difficulty, but outside of Grymforge the tactician difficulty is absolutely fantastic and shove is entirely non-existent.
I can wholeheartedly say I love it because as someone who played Early Access for countless of hours I know the difference between Balanced and Tactician by heart and it feels like the game was truly made and balanced around it by giving a ton of personality in combat and variety. But Grymforge is unfortunately the one special exception where everything goes to s*** and devolves into shove shove shove contest, even on such a difficulty which is just a shame as I expected an actual challenge during the Nere fight, not shoving comedy.
