Somebody posted the point on the WOTC boards, and several people agreed with him, that both of these books are very broken, if you use them individually, but if you allow both of them in your campaign, they kinda balance out. I'll repost this there if there's no particular consensus, but I wanted to ask here first because there's a certain house-organ feel to the WOTC boards sometimes, where it feels like it's heresy to say that something is less than l33t.
My son just picked up Exalted Deeds and Champions of Valor, in hopes that he can come up with an uber build that the party will allow because it's Good. Ignoring all the other uber characters that he came up with that didn't go over too well, even though they were Good, on account of that whole "uber" thing. Yes, I know. We have issues.
I'm going to be taking a more proactive role in what people can build and play in the next campaign and, to be honest, my son may not be happy in my next camaign; on the other hand, the people who insist on building pathetically weak characters may also not be too happy, either, so we'll see how it turns out. Like I said. Issues.
On to the real question at hand: Is the premise correct that allowing Exalted Deeds and CoV into my campaign, without balancing them with the Book of Vile Darkness, an unbalancing thing, or were the people on the WOTC boards nuts?
