Sounds much better. And what if you Dodge and it’s not successful your opponent gets a +1 bonus because you are unbalanced. But you don’t have to use a Fast Action to stand up. There have to be a penalty because you can Dodge every attack but can’t Parry with every weapon.I'm personally not a huge fan of adding in extra dice rolls during combat.I don´t like it eather. Dodging seems a very bad choice until having that talent on Level 2 or 3.
What about a chance to prone, perhaps if unsuccessful or a move roll to check ...
What about giving the PCs a negative modifier to their Dodge roll (say, - 2) if they don't want to fall prone? Then the talent removes that penalty.
