Ah, another "victim" of a peace offering. I had a store download problem with another EA game, could not download items I paid real cash for. It took me working with support for nearly a year to get it resolved. The gave me DAO and all DLC as a peace offering.
I had a heck of a time the first time I played DAI, that Rift confused me too - back up where I could see it and, too far away to interact, get close and can't see the darned thing. (Then I bothered to read the keybindings and, solved it. Like you, I detest tac cam, it isn't because of how it works or doesn't work, I don't like it in any game. You can't pause and tell friends what to do in a real fight, why do so in a game?
I think all that helped me not get as far off track as to what to do was playing the game Rift (By Trion) there you attack a mini boss at the center of a rift to close the rift so, I assumed I was supposed to do something with the center of the thing and, it was clear pretty fast that the mini boss wasn't going to stay there and take it like they do in Rift so, I had to find plan B.
