R5 skill 4* or wait to r4 5* Hulk Rags?
Hey guys I have a 5* Hulk Rags and I just need 1 more science t4cc to rank him up. Was hoping to get one from map 5 crystals but those no longer give t4cc fully forms any more. So it will likely be a long while before I get one. In the mean time, I’m getting skill t4cc in overflow and was considering r5 my 4* Thor Rags because of the synergy he’s got with my Hulk Rags. Gold and iso are currently precious to me, so I’d just like to know should I rank up Thor Rags first or wait a while and r4 my Hulk first? I’d really appreciate your feedback, thanks!
