My guy is level 25(or 26). How long do you think it would take to get to 30 in me2? I still have the other "big" dlc to go (excluding broker).
Have you done all the main quests/loyalty missions? What about the sidequests and N7 missions, or even the Firewalker DLC? Have you beaten ME2 before, which gives you a 25% XP boost? When I did my Adept Insanity run (the last non-NG+ run I've done in a while), I reached 30 with a decent amount to go before I ran out of content. Even if you haven't beaten ME2 before, I think it should be possible to hit 30 if you do everything there is to do. And if you don't go all the way, you should still retain your level when importing.
