You can still play through as a renegade the first run of ME2 and get a huge majority of the achievements, in fact getting most of the achievements in ME2 is silly easy, and doing the recruitments/loyalty of the characters still gets you more renegade than not doing them. So I don't see where ME2 achievements are necessarily paragon biased. I'm pretty sure that you can even get No one left behind on a nearly full renegade run, since you can resolve "infighting" with renegade options, and there's no forcing you to pick Morinth if you're renegade either. The hardest achievement for me so far, has been Paramour, because I haven't done a female shepard romance choice in ME2 yet.
