The burn being healed I can live with (though it still makes no sense, freezing something doesn't help a burn :/), but 100% accurate attacks normally don't miss unless the opponent makes an effort to dodge them, which he didn't. I know he has the speed boost and everything, but with the current mechanics that doesn't give passive evasion; unless a dodge is commanded a 100% move should hit. I'm really sorry that I keep on commenting on things like this, but it's a pretty big deal when I'm losing 20-some damage. You should probably check with other people (ask head ref Flora or come to #capasb on IRC and ask) before doing something like that to see if it makes sense/is ok. Really sorry for the trouble.
"Ok Seedstrike, let's keep up the assault! Lead off with another Seed Bomb, then go for another Swords Dance to prepare for next round before hopefully finishing this with a final Seed Bomb!"
Seed Bomb -> Swords Dance -> Seed Bomb
