So is it official that they are recharged at the beginning of each turn instead of the end of each turn like they were last packet (either way is much better than every turn)?
I much prefer the end of each turn, since it allows for more reasonable characters than otherwise. With refresh at beginning of turn, offensive fighters will nearly always be able to use their dice, and defensive fighters will rarely use their dice. Since defensive fighters need to be attacked, and also hit in order to ever use their dice, once ignored they are useless. So every fighter will tend towards the offensive side, because then they can actually use their abilities. Offensive fighters, will only need to hit AC 10, to use their dice for damage.
With refresh at the end of the turn, offensive fighters will still be in the same place nearly always being able to deal damage using their dice. While defensive fighters can parry/protect to their hearts content, and become better defenders in that if you try to ignore them than they become damage dealers (due to not needing to put effort into defenses).
Agreed, I much preferred the "end of turn" mechanic.
