I have spent SEVERAL hours in custom gangs.
I was having alot of fun until i realized when 3 gangs were on the field, the AI just lost it.
A ganger rushes out to do something, very diliblatly... gets to the location... seemingly waits for a second recalculates then runs back to roughly its original location.
Ganger entrenches as there first action wastes some AP and most of there MP recalculates..then just stands there for a good 10 seconds and may or may not just crouch in place.
Ganger spends the whole game running at the wall right behind where he spawned and couches and entrenches, if hes lucky his leader will use a tactical skill to buff him and he will actually do something the next round.
Gang in the light capture game flip 3 lights out of 5 then the last 2 gangers sorta give up and don't leave spawn area.
Ganger attack priority, im not sure if its bad or if its intentionally bad for the difficulty levels.
Ganger runs around map. does one thing runs back.... do something then runs back. all actions don't amount to much and didn't really have much prioritizing.
Ganger places trap, walks over its oh trap immediately after its placement. (I kinda dont think a gang should trigger its own traps but thats just me.)
and this is just the common issues. some times they do things so baffling its hard to describe with out explaining the entire match.
I actual really love this game. its fun. but some times its hard when the AI cant seem to keep its plan strait.
