@Tinker: Yes, but for the Transmuter to get those big numbers, he pays the opportunity cost of being locked into Human. The Crusader's damage is certainly more finicky and limited, but it's baked into the class. No matter what else you're doing, you always have the option of racking up some huge numbers, which isn't the case with the Transmuter. Plus, the math suggests that you have something like a 420% damage bonus, which is probably took something like 3600 CP, not an easy sum to reach even with Inner Mastery.
Basically, what I'm trying to get at is that it's a bit of an apples and oranges comparison. Human Transmuter is capable of crazy deeps, but that's a focused build; Crusader can just do it regardless, hence why it is going to look weaker in comparison.
