I was just in quite a frustrating situation where a party member accused me exploiting AI, and after talking it over with a DM I was told that sometimes retreat or hit and run tactics will be considered an exploit because AI cannot cope with them.
This was a quest where a mob of about 40 npcs are on a steep hill, many are spellcasters, and there may or may not be traps. One casts a spell that can and did do 100 damage instantly.
If you fight for awhile, get hurt and retreat down the hill, or retreat down the hill to get out of archer or spell fire, you get considered to be an exploiter because the AI apparently can't cope with you going down a slope.
It comes to a point where your expected to charge into that mass and all that can save you is popping inviz potions. Oh wait, thats an exploit too, because the AI may not realize they have to drink a See Inviz potion now.
Other party members had previously been shooting at the archers on that hill, this is clearly an exploit as well, because the AI spellcasters and archers don't know to get back out of range when badly hurt.
One of their spellcasters for some reason closed to melee, clearly we should've run away from it to give it casting room, because this is exploiting AI mistakes. Also it didn't cast Dispel, rather some other magics, clearly we should've dispelled ourselves to make up for that AI lack.
I'm a tad frustrated by all this, how far are we expected to bend over backwards to make sure the AI has a fair shot? The quest monsters outnumber and are often vastly stronger than any PC can hope to be, to me that is the factor that balances out the AI not always doing the tactical thing. A lot of the quest bosses, if played by a DM, can utterly destroy a party - if anything I've often seen the DMs hold back or seem to intentionally make mistakes because of this.
I won't be doing this quest anymore because I am expected to attack overwhelming odds without being able to retreat, but this AI issue is something that needs clarifying. The first time I ever did that quest, when I was a very low level and taken by the then experienced group of players, they did the same things I was.
There should be an ooc sign there : once you climb the hill you cannot go back or its an exploit.
This one hill is just one example of what seems to me a general murkiness or lack of awareness in this area, and one where desicions seem somewhat arbitrary.
For instance, is it an exploit to duck around a corner to break line of sight with a goblin archer? It comes running to the corner, rather than fans out to go around and get another angle. Are we therefore supposed to not dodge in this way? What about breaking line of sight to avoid spells? Do we need to stand and tkae that Fireball because the AI isn't smart enough to cast it anywhere but directly targetted on us? What about npc casters that tend to run forward, not away, when they're shot at?
Clearly some of the examples I've given are ludicrous and they were meant to be, to show that any of these could be considered exploits. I think the lines need to be clearly drawn therefore so that those who cheat, actually know they are, and where cheating is of a clear standard rather than varying from opinion to opinion. I certainly didn't believe anything I did was exploitive nor did others, yet others did, and it seems to be a general vagueness and difference of opinion in this murky issue of AI.
