Better value Rankup - R3 Onslaught or R2 Sunspot
I've been hanging out to R3 my Onslaught (unduped) and only 1/2 a T6 Mutant Catalyst away from doing so, but then I saw the boost for the next BGs season and seeing a few comments of how people react to Onslaught left me thinking that taking Sunspot (Sig 20) to R2 instead would be a more useful rankup, saving my T4A for some other rankup in the future (I'm already Valiant, this would be my 3rd R3). I already have Bishop at R2, Stryfe and Sauron are the other Mutants but not really considering them.
