And there you have the Knock-On Effect, Ladies and Gentlebeings: removing AoOs affects the balance between classes, the value of certain feat choices (and, recall that some PrCs require AoO-related feats as entry requirements. You could just remove them--but that makes the PrC more accessable. You could require them but the feat has no other value--that makes it less accessable. You could substitute in a new feat--but then you need to think about it ahead of time, come up with an appropriate feat, and most importantly, know that you have to do so before the PC gets to the right level, because they can't go back and change their feat choices. So removing AoO affects feats, which affect PrCs, which have the potential to affect the permanency of earlier feat choices, if the DM chooses the third path, here.)Crothian said:It makes it easier and safer to move around the combat areas
It weakens reach greatly
It makes grapple, tripping, and other options that usually provoke AoO easier to do
It makes casting and using missile weapons while in melee easier to do
It makes some feats like combat reflexes and mobility pointless
Those are some of what I remember when I played without AoO for a bit. My main reason for getting rid of AoO was we didn't want to use a battle map and it was simplier to just get rid of AoO along with that.
Chiaroscuro23 said:For some posters, the issue seems to be not so much "does changing one rule affect other rules, sometimes in unpredictable ways", to which the answer is obviously yes, but rather "does changing one rule make the game unplayable", to which the answer is obviously no. So whether you believe in this ripple or knock-on effect seems basically to depend on whether you think the ripples rules change cause are "big enough". And that's an issue about the definition of knock-on, not about whether ripples happen.

Okay, that's a more reasonable question. I think the answer is yes, 3e is more tightly integrated and better balanced, so changes will ripple more, and the change in balance will be more noticeable.ehren37 said:I thought the issue was "does changing a rule impact/disrupt the game more than previous editions".

The advice of the experts seems to be "just make something up" in some situations.
What happens when a Monk meets a Drow? You have to start making house rules. It is not even clear how the Monk works with the core rules standing alone.
