... In class rank to transfer from a high T2 to:
1) A slightly higher T2 verging on T1; or
2) A slightly lower T2?
No one can give you an answer without knowing the schools you want to transfer to. You might have problems transfering to certain Tier 3 law schools that are not transfer friendly even if you're in the upper half at your high Tier 2 and on the other hand, you might be easily accepted to a lower Tier 2 with the same grades and vice versa.
Tell us what the schools that you want to transfer to, some of us can give you an accurate estimate. Don't worry, every year, countless people try to transfer to almost any school (even Tier 3 law schools can receive up to 10 transfers each year and that's not just applicants), we won't be able to identify you.
