Against the point? I feel that it changes very little in the scope of the competition. With a 10 level prestige class that doesn't advance spellcasting nor psionics, we probably won't see builds built around manifesting or spellcasting anyways. Therefore, how you qualify for it... doesn't matter to much.
We'll just have to wait and see what the big man says.
Eh, if given a PrC, I am not wont to shift the rules. That's just me though. Helio has the final say, and I'll happily judge anything presented to me assuming it's legally done.
All that I say applies only to myself. You author your own actions and choices. I cannot and will not be responsible for you, nor are you for me, regardless of situation or circumstance.
