I have to agree, i have played the game on tactician mode whole time since launch and it feels like its normal difficulty, not that hard. But it seems to depend on classes your party has, some are clearly superior and some are very weak, mostly casters are weak and fighter / monk is strong.. you can tell it that often githyanki groups are most difficult battles and they are 90% fighter or monks...
Before you disagree try make lvl 8 group of 4 sorcerers or 4 wizards, then compare it to group of 4 fighters or 4 monks.
