Have to agree on the names. Golden Wyvern Adept is meaningless and will only be annoying to run. How about when an NPC has a feat with this sort of overly-florid name? (Do NPCs have feats, anyway?) Presumably he'd have the feat name on his character sheet, and unless the GM has an encyclopedic knowledge of the rules he'll have to look it up before using it. And this problem will only get worse as supplements start coming out and the feat options pile up.
Surely something a little bit descriptive would be better? I can cope with the names not being completely prosaic, but a bit more thought being put into the names rather than just picking an adjective and a noun out a hat would have been nice. This one could have been called Islands In The Fire Technique, or something like that. This way the name actually means something. What do wyverns or gold have to do with shaping evocations anyway?
Also, does anyone else think the 'Adjective Noun' naming convention might be limited to higher-level powers and abilities? Both this and the legendary 'Dragons Tail Cut' would appear to be targeted mostly at fairly beefy characters. If this is the case, it makes the whole business a fair bit more palatable imho. A 5th-level fighter might have Weapon Focus and Defensive Expertise or something, and that seems reasonable, but when he's 25th it's a fair bit easier to see him having mastered Razor Hail Technique and Cut of the Nine Winds. Very Epic.
