Those who know my character Blackhawk also know i have extensive experience with player an AC character.
Here are a few tips:
1: The best trait combination for 140 ac is kamikazee, liwewire, dodger +. If you want to use CA MK II take dodger (rank 1) aswell. Having 120 AC is pointless, trust me. Either go 140 or nothing.
2: For TB you character should have an uneven number of action points, such as 9 / 11 / 13. This is because, in order to get the ac bonus you can only use less than half your AP. With 11 AP you can use 5 AP and still retain AC bonus in TB. If you want to burst BG you need 13 AP to retain AC.
3: NCR Rangers, VC and Hub patrols cant hit you and will run away, with exception of shotgun (+20 hit), needle gun, 14mm and flamethrower users. They will only try shooting at 1 hex though. Sniper Rifle users will try to shoot at ~10 hex, but will miss alot. NCR army hunting rifle users will allso try to shoot at ~10 hex, but they miss alot too. The good thing is, the build starts working alredy at lvl 15 (dodger+) which means rangers, hub and vc patrol cannot kill you.
4: Because people miss alot, jinxed is a good trait, even in PvE.
THAT BEING SAID: Sure you can farm these mobs with a 10mm in bluesuit, but the AC bug makes this method panfully slow; When critters cant hit they run. When they reach the grid they will freeze, and use all their time (30 seconds someone said) EACH TURN. Imagine you have to wait for 4-5 VC patrol to each use 30 seconds, each turn, while you can only shoot once to retain your AC.
Conclusion: Dont farm with AC build until the bug is fixed.
