If you just want to play your character, don't care about tactics what so ever and just roll through, normal is good for that. Hard is still very much way too easy, but requires you to at least move your tank in first and hope the AI works from then on. Hard in DA2 was pretty good, as it felt balanced. Hard in DA:O was sometimes extremely unforgiving, but overall it was challenging and constantly fun.
Most of the stuff that made DA:O such an amazing game, at least combat wise, is sadly not to be found in Inquisition. What I miss the most is the advanced tactics and behavior control which made it so that you could automate a lot of frustrating micromanagement that Inquisition requires on hard, as the AI of your party members, at least your tank, is quite awful. In DA:O you still hade to micromanage, but you could totally let your damaging members do most of the work themselves, even combo stuff themselves in DA2. I really miss this and I don't see why they couldn't just add an advanced option for the tactics. A shame.
