D:OS is not very hard, even tactician isn't that hard especially if you already played classic. It's a one shot game that becomes trivial once you've played it unless you're absolutely not paying any attention.
In the early days it got a rep for being a hard game because in the early game level matters a lot and tons of people went off trying to fight level 4 enemies as a level 2.
I do agree that a "hard mode" before tactician should return, there's a whole thread on it on the D:OS 2 board.
I wouldn't describe any builds as unusable in tactican. Sub-optimal sure.
