First, people need to remember there were three other feats there which didn't have a silly name, but anyway.
The problem I have with most of the names, is that while they often have a good fluff word which is at least as descriptive as "combat expertise" or "empower spell" but there's two things generally stopping people from getting that, firstly, we're not used to it (remember, anyone actually
taking Golden Wyvern Adept will already be a 10th level wizard, and will know that "Golden Wyvern" implies spell shaping and sculping) and secondly, because some idiot tends have tacked on a third word that doesn't mean anything.
Panther Strike = some sort of natural attack, implies speed, silence and deadliness - makes sense
Lightning Panther Strike - doesn't really mean anything
Flame magic = duh
Hidden Flame - meaning more obscured (especially since it contains light spells, which seems counterintuitive)
Iron magic = magic to make things tougher, probably defensive magic - makes sense
Iron Sigil Tradition - Rune magic of some kind?
If someone told you "Gold Magic" involved making your spells more malleable, that makes sense, it's easy to remember, and fits into most campaigns, in fact it fits fantasy roleplay far more than a "conjuration school" (and no ever complained that this required you to put a specific "school" or university into your world, btw), but "Golden Wyvern Adept" hides that behind a meaningless third word that adds nothing, and confuses the point.
To me it feels like they wrote up a bunch of good (at least decent)
fluff, and then
let a 15 year old at it.
But maybe I'm alone in this.
