In previous Dragon Age games you would assign orders and then let it play out, according to these guys it doesn't work like that anymore in this game. DA:I is allegedly designed around selecting a character and then swiping away in 3rd person mode, while only occasionally entering tactical mode to issue orders for teammates.
BTW, you should probably play the game before you claim as a fact that tactical mode has vastly improved.
You killed bears and bandits in Lothering for maybe 30 minutes in DA:O, not six hours. These guys played DA:I for six hours and said that they ran into numerous fetch quests during this time.
Why should I play the game? There's been ample gameplay vids out there that CLEARLY show you can play the game in Tactical Camera mode (as in, they actually did it), a mode which we KNOW features autoattack, and has none of the "issues" these particular previewers mention.
Furthermore, we also know for a fact that the Tactical Camera mode is improved over DAO: it has full camera control (so you're not locked in quasi-isometric view), displays enemy stats and effects, shows movement paths, AND is now available on the consoles. These are all, objectively speaking, clear improvements above and beyond what we had in DAO.
And yes, it's true that they were several (not 6, however) hours in the open world of the Hinterland, and saw numerous fetch quests, but the fact remains that they were still just in the exploration aspects. That doesn't tell us, or them, just how good the story quests are, because their preview stopped the moment they tried to progress the story.
It does tell us, however, that the exploration aspect of the game consists of light quests, some of which are fetch quest. But that's hardly new to anyone who plays open world games. I was using Lothering as comparison because, well, there's nothing else that compares: DAI's exploration aspect is new to Dragon Age (not doubt why the preview focused a lot on it). But the existence of fetch quests doesn't mean the quest design is bad, it's pretty standard for open world exploration, and the previewers were not allowed to progress the story anyway, so cannot render a proper judgement of the quest design in general.
That said, we do know there's more than fetch quests in DAI's exploration areas, as indicated by many other previews.
