Perhaps I gave the readers too much credit in assuming they would be able to make the correlation of
"the down time' and the restriction change from spell to JA or stats. Noting that I did not convey my thoughts in the best manor, I tried to further explain it in order to clear up any confusion.
That is correct, there is nothing wrong with the spell set system.
Maybe I'm the only BLU that would like to have access to all of my spells without having to change them.

However this would provide a work around for proc-based events and the down time that comes from having to change spell sets.
