No comments on my feat?
*sniff* That hurts, guys.
I'd have to try it in a game, but my gut feeling is "Yes", too powerful.
Imagine a high-level party being attacked by one high-level spellcaster on the ethereal plane. Initially, when the spells begin to fly, the party will think their opponent is invisible. As
see invisibility will see ethereal, they'll spot him (but will they know he's ethereal? Not sure about that...) But once they spot him, they still can't do much. The "tanks" are worthless, unless someone in the party can make them ethereal. As for the spellcasters, only a very limited selection of spells can affect the ethereal caster. You could easily have a TPK - the best an unprepared party can hope for is to escape relatively intact (meaning alive).
Worse yet, imagine your pc's using this metamagic feat against your BBEG's...
It comes down to all the defensive enhancements from being ethereal - a party that knows what to expect can probably handle it fine. An unprepared party (or BBEG) is in a lot of trouble.
edit - I just thought of this: imagine the party is underground. The attacking spellcaster not only has all the immunities of etherealness, he can pass through cavern walls at will, then return to get in a surprise attack, rinse and repeat. The more I think about it, this feat is
very powerful.
