Don't let anyone fool you. Xinyan is solid physical dps. Granted having C6 really makes a difference, but she can be useful, especially with a limited roster for a new player. Plus she's claymore AND pyro, which comes in handy traveling about. If you don't mind rolling on the current character banner, I also stand by Thoma as a solid shielder. His ult does a lot of good. Heizou is new and I'm still building him so no opinions yet. Ningguang is useful in many ways, but I've never been able to get her as good a dps as she supposedly is. You still have a lot to do, quests, events, etc, so you'll build up plenty of wishes early on.
