Sejs said:Which leads to say that monks have Evasion. Rogues have Evasion, but this is a different ability that is not, in fact, Evasion. My personal oppinion has been already stated on the matter; that while they share similar function, the different name and lack of cross-compatability note says they're different.
It could be argued that since Prescient Sense applies under all circumstances that (standard) Evasion would also apply, the function of (standard) Evasion is subsumed under Prescient Sense.
If the purpose of a prerequisite is to say "You must be able to do X before you're qualified to learn Y", then what's the logic in saying that "Well, Mark the rogue can learn Y because he can avoid damage on a successful Reflex save (but only when he's wearing light armor or no armor), but Jane the oracle can't learn Y because she can avoid damage on a successful Reflex save (in any kind of armor)"?
To look at DM Matt's cancer analogy from another angle, stomach cancer is a form of cancer and skin cancer is a form of cancer, but treatment for skin cancer won't help alieviate stomach cancer simply by virtue of both afflictions being cancer. For skin cancer treatments to work, you need to have skin cancer. So it goes.
On the flip side, imatinib mesylate (Gleevec) treats both gastrointestinal stromal sarcoma and chronic myelogenous leukemia (two completely unrelated cancers) quite effectively.
