I don't think they weigh your cGPA too heavily. My cGPA is pretty tragic but I have a strong L2 and a sub-par LSAT and was waitlisted last cycle. I know that's not an acceptance but I really do think they prioritize your L2, and favour a strong upward trend. (I have friends who were accepted over previous cycles with lower cGPA's but strong L2's as well).
I was accepted by Western this cycle with with a 3.08 cGPA and a 3.65 L2 (and a 167 LSAT). Mind you, I also have 2 masters degrees and got an A- average in both (both were course-based). I think cGPA does matter, but they account for how long ago your undergrad was and what you've done since then, and whether you've proved that you could probably do better if you were given another chance (and ergo succeed in law school).
