You don't have to plan ahead in Origins, literally. The main reason why you have party tactics in origins, is because the AI is a bit on the dumber side. DA:O combat has some depth in the power combinations that's a bit more than Mass Effect but its core mechanics are weaker than Mass Effect 2's.It's automated if you set up the strategies you want your party members to take, which is inherently deep. You are thinking of and addressing situations before they even happen. Plus there's a ridiculous amount of abilities and builds.
There's no much to ME other than shoot the target, take cover and use an ability.
