Are there any classes who have access to both Flame Blade and Fireball and can use both effectively?
Druids with the Fire domain get both, but only get Fireball in the very limited domain spell slot.
Theologian archetype Clerics who worship Sarenrae and take the Fire domain get both, but now Flame Blade is competing for the same 3rd level spell slots that Fireball uses.
Magaambyan Initiate archetype Arcanists can get both without competing spell levels, but their BAB is awful, so using Flame Blade pretty tough.
Enlightened Bloodragers can get both and have great BAB, but extremely limited spells per day.
Nature Bonded Magus can get both, at the correct levels, with decent BAB, but the archetype gives up Arcane Pool and Spell Recall for stuff that totally isn't worth that loss.
Is there any way to get both spells on the other 6th-level casters?
