I agree with assertn here, the Sharingan for everyone but Itachi has been more of a support tool rather than offensive(it was only used that way on zabuza in one fight for non-Itachi sharingans). It is true that Itachi uses it's one(maybe more...) offensive tool often from what we have seen so far but before he knew how to use it he must have done other things(it was implyed that he was good with shruikens) and I don't think he would have simply forgot about those skills and only focused on the Sharingan, but alas we must wait and see =).

Also using the example of oro's techniques being taken away in comparision to disabling the Sharingan is kind of unfair because it took away his arms not just the techniques. Also as you said not looking into the eyes only gave gai about 50% win rate so then if the gai style person was on the same level as itachi he would only have a 50% win rate if we are comparing the two so it's still not that great.
