Jump update and SP resets?

Don't think that's really a problem even if we didn't get the SP Reset. A lot of the skills were converted. Remember Achilles for DrKs? The points allocated in that were automatically transferred to Dark Impaler.

The skill before and after don't have necessarily the same priority in maxing.
For F/Ps fire demon becomes mist explosion. While one was almost useless and maxed very late, the latter is a very good skill you'd want to max early.
