Although Mora is for entertainment purposes only your opinion on chanting is valid. Different people prefer to cast in different ways, some make their spells rhyme, while others use long elaborate rituals or chanting. It all depends on how you prefer to work.
Mora may be a bit of fun but I wouldn't trust her for any kind of real answer.
Mora is a program and only on here for entertainment nothing more. Expecting realistic answers from her is like waiting for the Earth to lose gravity. What ever opinions you have are based on your personal thoughts.
