I honestly didn't mind the sub transformations Believix offered, either. It was done correctly, and it really did feel like an extension of the Believix power. It makes sense; Believix has a technically limitless power source as humans are always being born, all that energy has to go somewhere (manifesting itself into the Gifts of Destiny). Like you said, it opened the doors for so many things, and gave satisfying explanations for most of everything.

Another way to look at it is that only those chosen by fate and Destiny receive these gifts, as Sophix and Lovix are presumably rarely used. I can see them being used in Pre-History if the domains ever warred with each other: so that the bearers of peace can tough the elements of each kingdom. That furthers the idea that the Ethereal Fairies are sort of like the Fates, but I'm trailing in my endless sea of fan explanation.

Faragonda mentioned that the Earth Fairies used the elements as an extension of their power, so nature and ice power-ups weren't far off, and only furthered the idea of separate domains for the Major Fairies. The special wings also proved to be useful, and they were hardly ever used in overkill, in my opinion. Same with Fairy Dust in S3.

Tynix felt incredibly useless to me, even more so then Harmonix. The only thing it brought was miniaturizing to access MiniWorlds, and I'm sad that warranted a new look. I think I liked the way the two forms were balanced in S5 - they weren't. Sirenix came in later and Harmonix was lost, but it made things feel more like a mission accomplished, more finite, and less like a "only needed for this dimension" thing that Mythix and Tynix have. I don't like they way those were handled.

Power and increase in strength is so very rare to see now.
