First, it allowed me to try to cleave twenty times into the Hill Giant with class levels, who clearly would have been a challenge otherwise. He died, of course. I thought this part was implied by the context of the discussion.
No, when you say "I killed 30 kobolds in a single round" that does not imply "I also killed a bunch of other stuff too". Still, why exactly were the kobolds drawing piles of AoOs? They aren't stupid, why did they note your capabilities and spend lots of time milling around within your reach? Plus, you basically used a significant feat chain, several spells, and a fair amount of resources and essentially defeated a single opponent in one round (the hill giant, the kobolds don't count, they are too low a CR to actually be counted). When you expend several spells and the benefits of a feat chain, you expect to be able to handle an opponent.
Second, this was only part of a larger encounter; the DM was throwing giants, vampires, trolls, ogre mages, a small dragon, etc. at us and decided to add a bunch of kobolds to crowd the space. They'd set up flanking opportunities, Aid Another, and in general impede our movement. (Oh, and act as food for the vampires...). Fireball was out of the question due to other constraints (hostages), and we didn't have Chain Lightning.
That's not really a "kobold army" then is it? That's "kobold cannon fodder" plus a bunch of actual opponents. Is it any wonder that they didn't last a single round? I'm still not seeing why a combo involving a feat chain plus the expenditure of multiple spells to kill off a bunch of mooks and (now in your revised version) a mid range opponent is a problem.
Clearing the entire population out in one round definitely helped the outcome. In that situation, they're not thirty individual CR 1/4 creatures, they're more like a trap that resets itself until you destroy it; the threat is not in the damage they do to you, it's in their ability to impede you against the others. Throwing hordes of "popcorn" creatures at the PCs has a lot going for it. Like someone said earlier, they can group-grapple half your party while a few bigger enemies wipe you out.
They could, but then again, a horde of "popcorn" creatures
isn't supposed to be a challenge for a 10th level character. So it should not surprise anyone when they
aren't. People wanting to throw a horde of kobolds, or goblins, or whatever other sub-1 CR opponents at 10th level characters and have them be even
remotely useful are just engaging in wishful thinking. They aren't, and won't be useful. The problem isn't that Cleave-AoO is broken, the problem is that "mook" opponents are not effective against mid to high level characters. Stop using them against such characters if you want something that will pose an effective challenge.
"Enemy" means whatever you want it to mean in this context. This isn't a magical ability; it's a mundane Feat, representing combat skill. If I decide to attack someone, what does THEIR intent have to do with whether the feat can be used?
No, it means enemies. Snails cannot threaten you in any way. Hence, they are not enemies. Sorry, that dodge doesn't work, and the only people who think it does are people trying to "prove" that cleave is broken.
