Regarding the new spell file and such.

[regatta]

You can still save spell sets. I'm a cleric so what I've done is made spell sets for whatever situation I may encounter. A spell set for group healing, spell set for raid buffing, spell set for resist buffing, spell set for solo'ing (both undead and live mobs). It's still almost just as easy as it was. No reason to make reasons why it should be like it was when it's not going to change back. Just adapt-and-overcome.
