I was about to argue with Jamie/Euthymios, but then I got confused again. Here's what he says:
There is no line under the MISSILE 2/1 heading that allows for Fire 2x and Move 1/2 while it should be possible every other round. Essentially, there should be a line for Move 1/2 - Fire 1-2x, and one for Fire 1-2 - Move 1/2. The only difference between Melee and Missile should be that if your actual Missile ROF is 2/1 it is reduced to 3/2 if you do a 1/2 Move during one of your phases while in Melee it stays 2/1. So assuming you know that if you move 1/2 your rate of fire drops with a missile attack, then the little subheading (For 3/2, round 1 is 1/1 and round 2 is 2/1) should be enough to tell you which heading to look under.
For example, I normally have a 2/1 ROF with my bow. I decide I want to move 1/2 and fire. Doing that makes my ROF 3/2. I look at the chart and see that "For 3/2, round 1 is 1/1 and round 2 is 2/1". So for round 1 I use the MISSILE 1/1 heading on the chart and Move 1/2 - Fire. For round 2 I use the MISSILE 2/1 heading on the chart which *should* have the options to Move 1/2 - Fire 2x and Fire 2x - Move 1/2. The only time I would be using the MISSILE 2/1 heading if I was moving 1/2 would be every other round starting on round 2.
I think what he's getting at is that if your base rate is 2/1 and you decide to move and fire (reducing your RoF to 3/2), in round 1 you follow the 1/1 section of the sheet (move half and fire 1 or fire 1 and move half). In round 2, your effective RoF should be 2/1. Jamie is saying that he thinks he should, in round 2, be able to take his 2 shots in either phase 1 or phase 2 and make a half move in the other phase, but the option to fire twice and then move is not on the sheet--as if the RoF reduction were cumulative.
Ghul, you said earlier in the thread that firing your full complement of shots (except at a 1/1 RoF) ends your round.
So I guess the confusion is that the book doesn't specify that for a shooter with a base 2/1, even with a RoF reduced to 3/2 because of movement, on round 2 (effective RoF 2/1 again), the two shots must be taken after your half movement, not before. Does that make sense?
So he's saying that either the Combat section in the book should be amended to make it clear that no matter what, firing your full complement of shots for any base RoF above 1/1 ends your actions or the sheet should have a line under MISSILE 2/1 for "(1) Fire 1-2 / (2) Move 1/2 IFF second round of moving and shooting" or something along those lines.
Or as he puts it, "Basically, if your ROF is 2/1 and you can never get more than one shot off and move in any round (as the chart implies) then your ROF has been reduced from 2/1 to 1/1 not 3/2 as it states in the text."
