You can get a new Autobot Ratchet fairly easily by running missions 1 and 3 in Crimson Skies (Autobot campaign first battleground).

I almost did the same mistake but, since I had noted down the prices most cards would sell for during the event, as soon as I noticed I wasn't getting nearly as much money I cancelled my sale and decided to wait more (and basically only sold the R1s that were overflowing from running missions).

Also, does anyone know if there is any formula for the exp you get from upgrading? I'm pretty sure that the amount you get is based on how strong the game thinks your card is (which, while having a strong correlation with rarity, is not strictly based on that), but I was wondering if there any other factors, such as faction or even using the same character?

Since I'm a bit superstitious, I saved up a bunch of R2 Divebombs and Razorclaws for when I get the raid cards for the next event :P

(if they do give a bigger exp boost, then I guess I'll know really fast ; )
