Thanks, Pryde! I've never let this drift far from my mind, I've just been trying to figure out two things: Whether to change the formula to Long/2 (since Long range damage rarely affects game outcomes), and how to calculate Protomech AV.
If I do them as individuals, the AV comes out super-high for a single Point. For example, one Siren has an AV of 16, which is reasonable for a light unit of its type and damage potential. However, that makes just one Point come to 78 AV; considering that a Company-sized game rounds off at around 300 AV, and that you are supposed to move the entire Point at once (giving them a disadvantage in initiative) that just seems high. Not TOO high, mind, but high.
Just basing the AV on the card itself still comes out FAR too low, as well. 22 points for five M16" SML 1/1/0 AS 1/1 SRM 1/1 units? Es no bueno.
Well, I'm going with the former option. Even if it's high, the initiative rules about counting units do balance out the disadvantage of moving 'five' units at once.
