There are already achievements. Check your codex.

I got mine yesterday, ordered off of Origin. Patience, my friend. It will come.

All the (whatever amount) of early access was meant to be for is pretty much incentive to order the game as early as you can. Bioware could have just as easily said 'screw you guys' and not given any early access time at all. In other words, there's no point in complaining about it. Just be happy you're getting any at all.

You also want to stand around and wait for mobs to respawn because people are killing the things you need every 2 seconds or so?

I really don't care which wave I get in through. I'm just glad the long, agonizing wait is finally (almost) over!
