Just have a little patience till the tac cam is working properly, then you will have the option to play the combat as in Origins if you so like.
Yeaaaaah.... no.
In Origins, I set up the tactics directives and switched characters to issue commands only a few times during some extremely tough fights. The rest of the game was me controlling my character (you could say I was.... *gasp* .... role-playing ...) and my companions following the general plan and attitudes I had arranged with them beforehand.
And if we are talking DA2 - check out the videos of any of Arelexxx's guides in the DA2 forum section. That's how I expect to play a Dragon Age game. At the moment, that's not possible for Inquisition.
I think there were two aspects to DAO that were valued by the gamers - Tac Cam and Combat Tactics. Both gave you a lot of freedom and control over the flow of battle; the first allowed for a lot of pre-planning and micromanaging, if you so wanted; the second allowed for reducing micromanaging to the barest minimum and even more immersion in role-playing your character. I believe people said "I love Tac Cam", because they associated it with having and exploring a lot of tactical options, they did not necessarily mean having a top-down isometric view.
Right now, Bioware has f*cked up the first aspect (aside from the terrible PC controls issues) by not having Tac Cam and Action Cam talking to each other and has completely removed the second aspect.
Also, they have removed auto-attack, which would improve gameplay experience by at least 50% IMNSHO. I'm not touching a melee main char with a ten foot pole until that one is fixed.
