I never see these problems. There's always a bot going for the main objective, usually at least 1 for secondary, and they definitely don't just sit back killing. Playing on PS3, so I have to use the bots.
The solution is simple and already in quake wars. Make skill and tactical difficulties separate. max out tactical for hard-level intelligence, minimize skill for easy-level bot shooting skill.
Easy and Normal difficulties probably have dumb bots, I always play on Hard.
I am playing on PS3, too, but on Normal (and now, Easy).
Why would I want to play Hard?
I've always played Normal or Easy in FPS games (my aiming's not great), so why should I be forced to play Hard just to get good-ish bots?
People tell me to play Hard...but, isn't that ignoring the problem instead of addressing it and hoping it gets fixed/patched/tweaked/improved?
Should we sweep all complaints under the rug and pretend they don't exist? Do you think the devs should turn a deaf ear to this? Don't they want to improve their game?
I hope people and reviewers' criticisms get heard by the devs. They need to listen if they want to make the games better to retain some of their audience and/or gain new audience, etc.
Alright, so i've done some looking about. This is exactly how it works...
The higher your level, the stronger the enemy AI is, and inversely the weaker YOUR ALLIES AI gets. I also believe the bots begin cheating at some point as i've started to get 1 shot...
The more your winning, the dumber your allies get and the enemies get better.
If your ~2 minutes from loosing, your allies START to get it together, and the enemy STARTS to get weaker. Not enough to make a difference if they've been dominating you the entire round...
If you win a match, despite the difficulty your on, the enemy AI will suddenly get stronger...
Your "settings" have little to no effect on how the AI handles. Over all, they just tend to make the AI dumber on a hole. I have to play on easy because it makes the enemy almost as dumb as mine, for at least the first half of the match, then they go back into god mode...
I think some of this may be true.....
I was playing Container City (Security mission where they get the bioweapon or whatever---never really cared about the story since there wasn't much of one) several times. One of those times I was sooooooo close to finishing the mission, I think----I was trying to deliver the bioweapon to whatever the end location was. My AI was actually helping me at each "objective checkpoint", I guess you could call it?-----but BARELY. Like 5 seconds away from running out of time for each one.
It's like the team AI gets a little desperate when time is running out and try to help me (sort of), but then, whenever it seems like we were going to finish the mission,
then the AI just.....I don't know what they are doing!
I think they got distracted by another Command Post along the way. Hey, guys! You were supposed to help me get
that darn bio-weapon to its location! But, noooo, they think going back to the beginning of the stage to keep killing the enemies and getting the Command Posts are the Primary Goals
of every lousy mission, lol!

Also, the enemy bots got really, really tricky near the end of the mission and were putting turrets and disguising themselves a lot.
Oh, my goodness, on a funny note, I hate enemy AI Operatives, especially since I can't tell if the dude was looking derpy because he's a derpy teammate bot or if he's just being a really smart enemy AI, heh! :laugh:
.........I think I may have found a temporary solution (at least for me for now)----because my AI dudes on both sides are obssessed with the Command Posts/Secondary Missions, I noticed if I try to capture an enemy Command Post or sabotage something of theirs, both sides just freak out somtimes, lol! Both AI (especially the enemy) start running towards the Command Post/Secondary Missions (though there are some stray enemies here and there guarding the primary objectives, ugh.)
^That's how I got all of the AI away from the gate (the one you needed a Soldier to blow up so the big Bot thing can pass through) in the beginning of Container City. Because
both AI are too busy killing each other and respawning to get at that Command Post (I think it was a Supply one?), I was by myself and had breathing room to become a Soldier
and blow that darn gate up.
......It's kind funny that I had to be forced to transform into a bad**** CoD Lonewolf player just to complete parts of these missions (and that Datakey one) when working with these AI bots when the whole purpose of the game is teamwork, lol! :hehe:
I'm going to try my best to deal with the AI until SD comes up with a patch/tweak in the future (and I'm sure they will, after they finish with more important technical things
like online lag, lobbying, etc). ^_^
