The "argument" may have been in thinking that somehow, every time you Take Aim, you would add another +3 to the roll.
Yes, that is exactly the way it I described it, and a way in which it can be read. Unfortunately nothing was presented to refute my claim.
Which is not the case, since Take Aim only builds a cumulative +1/+1 up to half your Willpower's worth. So a gunner with Willpower 4 can Take Aim twice at the most. Which would be +4 Accuracy and +4 attack, total.
Yes, aiming will only help you build up a modifier up to wil/2 rounded up to accuracy or dice pool when aiming. However, the sentence under "Wireless Smartgun" could fill this limit more quickly.
I hope I can clear my intentions with an example.
Case 1:
Lets say I have Agility 6, Pistols 6, Willpower 5 and a
non-wireless smartgun and implanted smartlink connections.
My pool for shooting normally is 12 dice.
I can use "Take Aim" for
3 simple actions and get 1 die per simple action which means I would have 12 + 3 (aiming) = 15 dice.
Case 2:
Lets say I have Agility 6, Pistols 6, Willpower 5 and a
wireless smartgun and implanted smartlink connections.
My pool for shooting normally is 14 dice.
I can use "Take Aim" for
1 simple action and get 1 die for the normal "Take Aim" action and +2 dice for a "Wireless Smartgun" 14 + 3 (aiming) = 17 dice.
Now lets up the willpower to 11:
Case 3:
Lets say I have Agility 6, Pistols 6, Willpower 11 and a
non-wireless smartgun and implanted smartlink connections.
My pool for shooting normally is 12 dice.
I can use "Take Aim" for
6 simple actions and get 1 die per simple action which means I would have 12 + 6 (aiming) = 18 dice.
Case 4:
Lets say I have Agility 6, Pistols 6, Willpower 11 and a
wireless smartgun and implanted smartlink connections.
My pool for shooting normally is 14 dice.
I can use "Take Aim" for
2 simple actions and get 1 die for the normal "Take Aim" action and +2 dice for a "Wireless Smartgun" for
each simple action spent aiming, which means 14 + 6 (aiming) = 20 dice,
since under "Wireless Smartgun" there is:
"A wireless smartgun connection provides an assortment of bonuses, but this table only provides the bonus you get while using it to attack. When aiming (using the Take Aim action) with a smartgun system the shooter gets both bonuses with each action of aiming."
Again, because "both bonuses" could mean the chosen bonus of the "Take Aim" action in the table and the "Wireless Smartgun" bonus of the table on page 176.
