Well this thread got rather feisty in the last two days...
At any RECENT interview (looking at E3 mostly), the devs stated "There is no import feature" right off the bat. I know not everyone clings to the interviews and some can say "I don't have the time" (though I honestly doubt it since you found the time to comment your distaste here), but really it's been known for at least a few weeks. Is there room for confusion? Sure, people misunderstand things and this idea has been changing constantly over a long period of time. It's hard to follow a bit if you get out of the loop a little.
If you honestly feel that your current playthroughs won't matter due to the keep being a questionnaire, you're mistaken (IMO). You know what choices you've made; that's the important part right there. That you made decisions regarding the werewolves and elves, for example. As you go through the keep, you'll get to pick those again. As for the "300 questions is too many to remember" well, while this isn't confirmed in any way, shape, or form, it would make sense that as you pick certain things other options become unavailable and narrow your remaining choices down. There is supposed to be some form of narration or pictures, something visually pleasing as stated in an E3 interview, so it's probably a bit better than some of you are expecting. If you do forget a choice, when the options pop up you just make it again. Once you see it, you should recall it. Or give different options a try to see if it changes your Inquisition gameplay.
If you're REALLY that resistant, wait until the Keep opens which will hopefully be before the game comes out (that's been stated, but not to a specific date as they are still doing beta invites). Take some time to mess around with it before you completely nix it. The only way for your previous playthroughs to really not matter is to not use the Keep and pick a default starter option like they offered in DA2. That would make previous playthroughs useless. They've been upfront about how the Keep cannot (currently) import previous save games directly. They have stated they're still looking into the matter, but at the moment it will not import old saves directly. If they can't do it due to the buggy quality of it, then they can't do it.
While that can be upsetting, that won't destroy the fun you'll probably have in the rest of Inquisition. I feel like some of you are not looking at the big picture which is to enjoy the new game and its story. Don't let a feature you're not getting (or that's different than you initially expected) ruin the entire game for you. They are offering a rather good alternative; you just have to be willing to try it first. (Again, the Keep should launch prior to Inquisition so you should get a chance to test it before the game. You can see if it's bearable then or if not, you'll do a default option, or even not get Inquisition altogether because you feel snubbed over the import feature.) Honestly though, you should at least give it a shot before you nix it.
