Yeah, it's, at least for me, less the use flavourful names, but the somewhat random choice of flavourful names.
Prime example: Golden Wyvern: "Golden Wyvern initiates are battle-mages who use their staves to shape and sculpt the spells they cast."
No connection whatsoever. How do I get from golden, winged beasts to battle-mages who shape area spells?
But this: "Stormwalker theurges channel spells of lightning and force through their wands." or "Serpent Eye traditions. Serpent Eye cabalists use orbs to focus powers of enchantment, beguiling, and ensnaring" is something I can get behind.
Stormwalker Theurge - it screams of elemental air, storms, the power of lightning.
Serpent Eye - Kaa's serpentine hypnotic is a classic.
Well, that's my opinion...
