Thaumaturge Spell Rotation
I've been mucking around with THM in order to unlock SMN and, while I'm at it, farm tickets from the low-level Moonfaire FATEs.
I'm pretty sure I understand how Blizzard and Fire work. Repeated casts of Fire drain your MP pretty quickly but do more damage, while repeated castings of Blizzard do less damage but replenish your MP more quickly.
I've heard people on these forums reference the THM spell rotation, usually in the context of players doing poorly in dungeons. ("He didn't even do the rotation properly.") Is this referring to an optimal way to juggle the different elemental spells for optimal output?
If so, what is that method at these lower levels? Should you be spamming Fire until your MP is depleted and then switching to Blizzard until you get it back? Should you be alternating back and forth between Blizzard and Fire? Is there some other formula?
Thanks.
