ITT: Hard more is hard, please make hard mode easy.
This is not at all what people are saying. They are saying that it's hard in a way which is uninteresting and very poorly implemented. This especially stands out when compared to Tactician mode of the PREVIOUS GAME IN THE SERIES which was done very well in a way which was challenging AND interesting.
Perhaps this was just inevitable because the previous game's Tactician difficulty was good because it was designed based on many hours of feedback from players, feedback which they simply didn't have past the end of Act I.
