What sort of Reaction, Body, and Armor values are you seeing yourself wanting to use Set-up against? Maybe we're using different notions of "high armor target," here.
Its possible I don't understand how the combat phase is played out but this is what I understand (below done with this character in normal combat in melee range, unwounded self vs Orc Adept with Militarty Heavy armor 4 helmet /and 5 points mystic armor, 9 body, 6 reaction)
Pistols+Agility+ modifiers(smartlink,pointblank, tacnet,In melee,recoil), and averaging 1/3 hits always rounded up.
11+6+2+2+2-0-0= 23
Without set up
BF 1
Attack
23/3 = 8
Defense[no dodge]6/3 = 2
8 - 2 = 6
6 + 3(BF) + 6(ex rounds) = 15
23 Ballistic Armor -2 = 21
Soak
21 + 9 = 30
30/3 = 10
15-10=
5DVBF 2
Attack
Since its average it again is:
14-10=
5DVTotal of
10DV average in two BF's
With setup
BF 1 Setup
Attack
23/3 = 8
BF 2
Attack
31 / 3 = 11
Defense[no dodge]6 / 3 = 2
11 - 2 = 9
9 + 3(BF) + 6(ex rounds) = 18
23 Ballistic Armor -2 = 21
Soak
21 + 9 = 30
30/3 =10
19-10 =
9DV average in setup and one BF.
Alright helps if i know the rules. It looks like until armor and body gets past these levels setup is useless Mathematically. It still could be better but guessing you would need to be against around 35-40 total armor + body before setup is useful. To bad I like the concept
*Edited to fix math again
