This thread sparkles me with new idea.

I think it would be nice if our 2hr BP has 0 reuse time.

First when we use those BP all MP are drained, and these BP has minimal MP cost.
The only way we can use it right away is to use Ether. but then there is dely when using Ether
So it doesn't make SMN over power if they take away the reuse time of 2hr BPs

For DNC their sub ability sharing the same timer can have different reuse time, so there is not a technical difficulty in there.

I know this might not improve SMN a lot, but this is my idea to empower SMN a tiny little bit.
