Couple of variant rules for Druids, your thoughts?

[Yitzi]

If it's longer, pre-combat buffs, can't they simply buff themselves and then wildshape in the first place (without Natural Spell at all)?

Not if it's something like 10 minutes per level (or even 1 minute/level at higher levels) and they want to cast it without burning a use of wildshape.

Or that's how I understand it, anyway. Maybe I misunderstand why Natural Spell is considered so overpowered despite the fact that you don't get very many benefits from the wildshape when you're casting (and therefore not attacking.)
