That's what the advanced combat rules are for. In advanced combat both you and your enemy selects both your actions (secretly) right away. Using this method you could both choose to attack as your first action or any other combination. Advanced combat normally is only used if you are in close combat (both are typically at Arm's Length distance) but you can use a combination of the normal combat rules and the advanced combat rules.Yes, the Melee Charge talent allows a combined move and attack:
"When you move from NEAR to
ARM’S LENGTH range you can, at the same
time, SLASH, STAB, PUNCH, or SHOVE. This
is called a CHARGE."
So, I guess that addresses part of my issue - I'd still like the option to hold an action though, so I move, then my opponent moves and we both have an action left for a proper fight. I suppose playing through the flow of the fight in my head, one of us will want to parry in that first exchange of blows, I'd prefer it was him rather than me though. Coriolis (and I know I keep citing it, becoming a bit of a Coriolis ) allows you to use your defensive action to either parry (reduce opponent successes) or counter-attack and damage your opponent at the same time he hits you. Maybe that could be an option?
So if you move so you are near an enemy (fast action) you can save your other action. This other action can normally only be used as a reactive action (if someone attacks you) but let's use advanced combat. On the enemies turn, he engages you (so you are at Arm's Length and both of you can attack). In this case both you and your enemy will choose a tactical card and since you both have a slow action left, that card can be of any kind (slow or fast). This means that both you and your enemy can attack, the enemy can disarm you and you attack or any other combination. I the next turn you both have two actions and you both selects both your tactical cards at the same time.
