The issue of the orcs move-and-attack is due to the fact that the GM chose to combine the move and the attack into one complex action.
To give an example with more variety.
Khabal is wearing a ring of "Aim Untrue" (1x day, instant spell)
Brandin has a loaded short bow ready.
Khabal and Brandin are each standing 20' apart.
Declarations:
Khabal "Activate the ring (10% action, then 65% recovery time), run 20' to brandin (25% action)"
Brandin "Shoot Khabal (50% action), reload (60%, or More than a round activity).
Initiative:
Brandin wins.
Short actions:
Only khabal has one, he activates the ring of "Aim Untrue" for 10% activity. (Rolls BSC and makes it)
Long actions
Brandin won initiative, shoots khabal 50% action. . .rolls well, but the aim untrue makes the arrow miss.
Khabal spends 65% activity "recovering" from using the ring.
Brandin begins to reload 50%
Khabal runs up to Branding 25%
Upkeep:
none needed other than exhaustion spent.
Round 2
Declarations
Khabal, "I pound on Brandin 100% with Martial Arts strikes Tier 1, he's got 120 OB, he declares 90/30 attack/parry.
Brandin "Crap, he's right on top of me, I drop the bow, draw my shortsword, and 100% parry with my 110 OB"
Note, GM chooses to combine Drop Bow (10%) and Draw Shortsword (20%) into one complex action of "Drop bow and draw sword" (30%)
Initiative
Khabal wins.
Short actions
Only brandin has one, drops bow, draws sword. (kindly GM chooses not to make him roll) 30%. Drawing places brandin into a martial stance, so his parry DB will work even if he looses initiative. (110 OB - 30 for action already taken is 80 OB, 100% parry is +80 DB)
Long actions
Khabal pounds on Brandin for 90 OB / 30 DB, attack on the MA Strikes attack table, tier 1.
If he's still standing, brandin can make his 0 OB short sword attack roll since he went full parry.
parry is normally just one opponant, but Parry on multiple opponents is covered in the section, give it a re-read and if it's still confusing, ask again.
