Hmm.. Here's my opinion. Thank you very much, Takeva, for making this known to the general public.

I was not aware of this bug, and will change my behavior (buy mists when I'm under 800 myth) for my 50 White Mage. I wish you all the best for your problem - hope SE takes a look at it and addresses it as soon as possible, because I do believe you.

Some people are set, molded and baked into their mindset and you cannot convince them, no matter how hard you try. If it's causing you any grief, I'd suggest not trying to convince them, as it's an exercise in futility.
