This is a video I made of the final battle on Tactician:
I soloed it in 3 turns as a lone wolf without ever needing any Allies or companions.
There is zero urgency or feeling of threat in the game, the entire concept of going out there to to quests for various NPCs in order to get them to aid you in the final battle is pointless .
As I can squash the dragon, illithids and the brain like bugs.
Because of that alot of the features the game gives you becomes just pointless cosmetics- the companions , the final battle Allies and the decision you made regarding to them.
It’s a lot of fun to feel like a god squashing everything and everyone but it would also be alot of fun if you beat a really hard game and the feeling of a hard won battle
