Yeah, AI mods aint perfect either. I used to tweak the parameters myself, to fine tune suspect behavior, but now the .pak file is so big, it takes ages to reinject the .ini file. I haven't looked it up yet, how to create a smaller .pak, which can be used as a mod.
Yeaterday I played two rounds on Valley, without AI mods/tweaks. On the first go, they were extremely aggressive, seeking the team out, refusing to surrender. I died, because one of them was one level below me and shot me through the floor.
On the second try, they mostly stuck to their original positions and didn't use wallhack. This time I used CS nades almost exclusievely, which seems to be the only thing that makes the AI willing to consider giving up. I managed to get an A rating.
The AI is very incosistent between playthroughs. I'm not sure how to feel about this. On one hand randomness is needed to enable replayability, on the other hand the difference shouldn't be this big. It feels like AI skill is based on RNG.
