Whole thing plays as ok-ish, if very repetitive, action-rpg on gamepad. PC controls are so retarded that I have no idea why anyone would inflict "Hold LK to attack" on himself. (and inflicting Inquisition on myself is beside the point here).
Do you mash buttons to strike on gamepad instead? I don't think it would make much difference since the issues aren't focused on holding or mashing, but on how the animations and targeting work. Unless the game is entirely reworked on a pad, which I doubt.
Anyway I do agree you need to play it without much direction for companions or "tactical camera." With Dragon Age 2 hard mode and up demanded you control their actions and such to a degree, and I disagree with people who say you can ignore companions on those difficulties, but this one requires little of that even on hard. It's more like Mass Effect where you focus on your guy and only tell them what to do in dire situations ("taunt this guy you motherfucker!"). I think a lot of people hate this attempt to combine "tactical" Origins style combat with button mashy action combat. The game is trying to be a hybrid which results in doing neither well, and I understand that. However I think the hybrid works much better as a mage, as it leans toward feeling more 3D RtwP as you line up AoE attacks, add buffs and debuffs, all while staying far away from the front line and the more melee focused clusterfuck.
