Well, for context keep in mind we already had threads with people complaining that STORY MODE was "still too hard".
Personally I'm fine with tactician. At no point I felt like the game was being either too hard "just for the sake of it" (something that happened more than once with WOTR at Core and above) nor I ever felt it got easy to the point where I was not having fun during the battles.
Admittedly, though, the boss at the end of Act 2 got slapped pretty hard with very few chances to hit back.
