I've nearly got three light elemental essences, and I really have no idea what I'd want to do with them. I think most people would say upgrading Epic Sax Big Band would be the right choice, but I find Big Band tedious to use for some reason. Diva Intervention Eliza and Doublicious are also options, but while they're both fun, I don't know that they'd move into being characters I'd regularly use even with the stat buff of moving them to Diamond. There's a lot of other options that also just don't seem to appeal to me. Could someone try and sell me on their favorite non-Epic Sax light element character, and why I should upgrade that character to diamond? Thanks in advance!
