No other Dragon Age game has had NG + so why would Inquisition? They are following the same pattern as always. Level 24 if you do everything and extend into level 30 with DLC and a possible expansion,
That's not a very good argument. Game evolve. Why shouldn't they? Just because something wasn't in one iteration doesn't mean it shouldn't be, and it doesn't mean it shouldn't be added to the next.
Anyway, I'd be all for a sort of newgame+, depending on the specifics. I really enjoyed that feature in the ME series. But in DA:I, I don't even need it to bring your gear or weapons or levels or skills through. Ideally, you could choose what you wanted to carry over. You could take everything, or just your face.
I just want to be able to play the same character again. I want to be able to use the same face, but maybe change classes, or change the worldstate. Of course, if we could save faces as presets, this wouldn't be necessary (come on Bioware, please add this). I think some way to do that is required.
Oh, and collectibles
Please, I'd take a newgame+ even if it just let the collectibles carry between playthroughs. My 2 cents.
