I don't know about anybody else, but I'm having a blast with PVP right now. I realize I'm very lucky in that I have a super usable if not perfectly optimal team which not everyone has, but the tension of trying to get perfect sweeps every round and trying not to break streaks is a lot of fun for me. Really scratches my Fire Emblem itch.
Still totally getting my ass kicked by Azura though. Gotta get good at using her against her team by making them split up when they shouldn't, but the computer tends to move her in weird ways that make setting up situations like that unpredictable. I've seen her very low on tier lists, which is insane. Just like Fates Azura was always low on the tier lists of people who don't know how to play Fire Emblem, she deserves much much better. Not sure I'm quite willing to call her the best character in Heroes like I do for her in Fates, but she's honestly close. She's definitely my main/possibly only want right now. Although I do like the idea of playing a Camilla theme team with Camilla/Beruka/Selena/Corrin and I don't own Beruka or Selena, so they're up there too.
