Well, there seem to be a certain rotation that are used
Thunder 2 > Fire Spam > Blizzard 3 > Thunder 2 > Fire Spam
Thunder 2 > Fire 3 > Fire spam > Blizzard 3 > Thunder 2 > Fire 3
If this is correct though, I have no Idea.... just it seems to be frowned uppon to spam Fire 3 and not doing anything else
