Well, like I said, the Wits build is not necessarily the best build around. Its main purpose is flexibility.
It allows you to spec into scoundrel and get more damage benefits from it. Because of the way stats work, the extra crit sort of evens out the lack of Int.
And I don't know if I agree with the best defense being a good offense. Surely this is the case in more nominal difficulty fights. But when you're in those really difficult fights, especially if you are fighting something above your level, your characters can die very fast. Having 50% extra magic resistance and 70%+ dodging can be a life saver in those fights.
I think most people have adopted the heavily offensive strategy because of the way tanks fail in this game. But with a leadership build, oddly enough your tank (leadership character) becomes your squishiest character.
I'm not going to try and argue that this is the best build or anything. But trying to say that it is an inferior build, is simply irony, when you are comparing it to a casting build. Anything that doesn't include very large swords or crossbows, is an inferior build, honestly.
Another build I had some fun with, was a dual sword evasion build, without leadership. The dodging was only 50-60%, and the damage was less than a two hand or ranged build, but that dodge was pretty handy!
