Isn't the fact that you have to pause more indicative of what we are talking about? The poor implementation of the tactics and the companion AI is why you have to pause more. Its the weakness of these control elements that hinders the controlability of your party, which in turn limits your tactical options because your companions are harder to control and less reliable in their actions.
See, this is what I don't get.
On the one hand, people say the game is less complex, with less abilities/spells to use, less customisation, basically less things to do in combat.
On the other hand, the same people also bemoan that you can't use the Tactics screen to basically have your party completely manage itself. Which one is it?
I replayed Origins recently, on Nightmare. It was easier than DA:I on Hard with FF on, thanks to all the potion hoarding and easy to use healing spells. Outside of a select few fights with mass CC or heavy damage, Origins is a cakewalk, even moreso if you use crafting or min-max.
Inquisition on Nightmare requires planning (for me at least), and timing when it comes to using combos or barriers. Given that the more squishy party members die in seconds, positioning them well is also pretty important. I agree that Inquisition has less options (I found most of them superfluous but that's neither here nor there). I don't agree that it requires less tactics, and the far more interesting itemization makes up for a good part of the lost customization to me.
Hell, in terms of customization, we lost crossbows (well, semi lost, hello Varric), duel-wield on warriors, and weapons other than staves on Mages as well as some abilities (which might have been needed, Mages in Origins had lots of redundant spells, and all classes gained lots of interesting passives). The latter is really annoying, if sorta made up by Knight-Enchanter. Apart from that, we still have armor customization (more than before), we have a much better crafting system, and one look at the Combat & Strategy forum shows the game still has lots of possible builds.
