No main until they add Pomme
I never getting good at a fighting game if I don't have a character I just adore. For SSBU it was Lucas, GGST it's Bridget, and the only other fighter I've attached to is Junpei from P4AU. They all have very different playstyles, but they all gave me the drive to learn their games. For Rivals, Pomme is my total favourite! I love the sassy pop star aesthetic as I'm a performer myself, and her fashion is just, so cool! But she's not in Rivals 2, and it kinda sucks that the game's collecting dust in my library while I hope and pray for her swift inclusion (exaggeration)
That said, I HAVE experimented with the newcomers, and they're all fun, but none have clicked.
TL;DR The character I best click with isn't in Rivals 2, so I don't have much desire to improve.
