1) I like the rule that says determine what cover is appropriate for the target. Cover in this case means people in the way.
If you miss by the amount of cover, then you hit someone in that line of sight.
2)Although I have melee attacks to be only 1/round (unless Hasted), I'm more lenient on missile/thrown attacks. If you have the %Act, you can reload/fire up to the 3 actions/round.
I think Talents could handle increased range, etc. I'm against Fighters getting more rolls per round. I feel the attack is what happens for the entire round of the attack, therefore no more attack rolls can be made, unless Hasted.
