So I'll start by introducing myself. My name's Lily, I'm fairly new to Guilty Gear (I've played through the story mode of GGXXAC with Bridget, that's about it) and have very little experience with Persona or Blazblue, so overall I'm pretty much a scrub when it comes to anime games. That said, I do have a bit more experience when it comes to other fighters, mainly UMvC3, Skullgirls, and King of Fighters.
I've been trying to learn how to play Millia in Xrd, and was browsing the combo thread for her. I get the combos, but I really don't understand how they work, which leads to me having trouble using them in an actual match. Marvel and Skullgirls have the Magic Series that all of their combos are based on, which makes them easy to remember. King of Fighters has it's Normal>Command Normal>Special series that makes combos in that easy to remember, but it feels like in Guilty Gear Xrd, moves just combo into other moves because the frame data and hitboxes work, and there's no real rhyme or reason to it. Is there something I'm missing or is that just how combos work in this game?
