When the guy said just because a feat is good doesn't mean everyone will take it, he was saying it in response to the "enchanters just got nerfed" comment. I don't think he meant it as a defense for overbalanced feats, just that for it to be a true nerf for enchanters that has to be a realistic opportunity that the caster will run up agains lots of NPC's with this feat chain. On the flip side, saying the sky is falling for enchanters everywhere is just as unrealistic as your rebuttle to his (however mistaken) argument for this feat.
Point is, nothing is free and those feats could have been used helping the tank get into a PrC that gave them mettle or something. But I guess then mages would cry about "evasion" vs. their Will saves. (Not that I'm saying anyone here is crying, but my players did and do, when NPC's mettle out of the way of harm, lol)
