Also, I recall someone saying that cards that are already trans-scanned will actually give less of an exp boost than cards that haven't been TS'ed.

So, if at all possible, you should never Trans-Scan your R2s or R1s. You will outgrow even the R2s very fast, since you can get half-decent R3s on missions (and if you've gotten a couple silver or gold medals from episode bosses, you probably got a few more R3s from those as well).

Actually, I now have so many R2s from gold medals that I have to sell some of my R2s as well >_>

(some of the worst ones are basically R1s anyway, both in power level and in sell price).
