I really enjoyed V8. I hadn't played since V5, so it was rather nice to return and see all the updated content.
Krystal is a really cool character. I also got the feeling she was the champion, but you never know.
As for the Flora/Florin situation, I sold her out. I went with Erin and was totally digging her character, so Flora just seemed like a brat to me. Sorry not sorry. Unfortunately, I wasn't among the wise many who saved, so my decision was permanent. I'm planning on doing a second playthrough on intense mode though, so I'm looking forward to revisiting that part and making a different choice.
Since I only fought Florin on Normal Mode, I didn't have too much trouble. My team is pretty slow, so good ol' Ampharos came in handy with Thunder Wave. Also, Vileplume was pretty godlike with the relative ease it had Toxic stalling and tanking pretty much all of his Pokemon.
Also, because I'm a major snot and like to correct people,
The battle actually happens in the rain, so that wasn't rng. Just the sweet blessing of weather.
