I say finish exploring EoP first, so you can see which class R4 gem you get, then use the cats to do your second R4. It will be easier to choose at that point...
@SirGamesBond i actually have a duped 7* Shathra, but i haven't R3'd her yet! I do like playing her though. I also just nabbed photon, still sitting at R1. Do you have a trick to using her on offense?@ TikkaMasala that's good advice, but i love so many of these champs on attack. I basically use all of them except enchantress and sentinel on offense!
Man, i know i should wait, but i still have 3 more paths to go for EoP! I'm FTP, so it's gonna take another month to earn up all the revives i need! :-P
