Did anyone who has a problem with damage on a miss, have a similar problem with half damage on a miss from a variety of arcane spells in prior editions?
I did. But there were a variety of reasons for it, as others have said, as it was an area effect. It wasn't damage on a miss ... on a attack vs. AC. It wasn't every round. And oh yeah, given that it was 3e - it cost you something.
For example, fireball did half damage on a miss in third edition, unless you had the special Uncanny Dodge ability, in which case you could dodge the entire fireball even where someone with a higher Dexterity could not.
You mean evasion. In 3e it was called evasion (later improved evasion). Uncanny dodge had to do with dodging sneak attacks. Also, AOE.
Did that cause similar issues with you? Or was it simply more believable that fire reaches between cracks in armor despite your dodging it (unless you have that special dodging ability), better than a sword wielded by someone with a special hitting ability?
I don't think anyone explained it that the fire somehow invaded the cracks in your full plate. Burned the exposed parts of your skin? Perhaps but not "into the cracks." Also, EVASION. Also, dodging behind cover gave you the same effect as evasion - so mechanically it still made sense.
As far as damage on a miss - no one else gets it, just a fighter specialty? How often can they do this? Is the explanation always going to be "I used my elbow?"
And for the record, I have always used every HIT to be a hit that deals actual damage/wounds to a creature. Even it is as minor as a scratch. That is what causes poison weapons to work, or damage reduction or any other countless things that hinge on HP. Saying that "it has always been hazy" does not make the explanation better - it makes it far worse. It says, "Hey this mechanic is already broken, as such I'm going to ram this unnecessary extra bit of brokenness into it and *crack* yeah, it fits see?" HP and AC don't make sense, so instead of trying to avoid making it not make sense, or trying to clean it up, or just trying to NOT emphasize it as much as possible they do the opposite and
metagame (for lack of a better term) another bit into it that does just the opposite.
