No, that's wrong. Both in that the folk regarding them as OP are not representative of a large enough portion of the gaming populace to be considered the "general" opinion, and in that the feats are not at all over-powered.
I disagree. In pretty much every discussion of that topic, on any message board or other messaging source I know of, those two feats are the most complained about (by far) in terms of balance. The people saying they are too powerful seem to outnumber the people saying they are fine 10 to 1 or more. And I am the type that almost always says stuff is fine...and even I think they are overpowered. And the reason they are overpowered are the reasons Zard is mentioning - too many ways to offset the negative and make the feat into almost-total positive. +10 per attack is a LOT. Too much, when the drawbacks are minimized.
