I also agree that Matt makes sense here. While I do see some good points in the OP, it is preferably not to over complicate things; and there is still a case by case scenario. While I understand the weather manipulation or magic feats shouldn't always scale to striking strength or durability unless there's in depth proof, I'm still certain about Ki based attacks scaling to durability at least. Newton's Third Law still applies to Boros collapsing Roar Cannon or Kamehameha's among other things, so I'm pretty sure durability should still scale. So IMO, I don't think any Dragon Ball character needs to have durability or striking strength downgraded; especially not durability. I still think Teen Gohan being stronger then Cell is the better assumption. Boros, not sure about striking strength, that could get a slight downgrade, but his durability is legit
Planet level. He briefly survived his own Roar Cannon, in addition to Newton's Third Law still existing.
Fire Emblem for example, much of the characters scale to my
Meteor Calc, in which every playable can legit tank, to it scales to everyone's durability, but all the mages just have
Unknow for striking strength, since they don't physically attack their foes. Though, Weapon wielders are
Town level physically regardless. So I think that verse is looking good. Another thing is that, if a storm feat is caused by a flying beast flapping their wings to create hurricanes or tornadoes, then that does sound like a striking strength feat as well. I also know every elemental bending technique in Avatar is done using a martial arts technique, so I guess that counts as striking strength?
Characters such as
Doctor Strange (Classic) and
Alex Russo are obviously glass cannons though. Since they're pretty much just all magic and little to no physical strength or toughness. Albeit, the former has barriers that can enhance durability.
Edit: I'll also need to sleep now, and I'm going to be busy with RL work the next couple of days.
