The OP seems very subjective here.

1) You can't really draw parallels to FFXI as far as HM/MP ratios go because, as Jinko pointed out, the algorithms in FFXIV are way different. It seems like the OP has a personal preference for having more MP than HP because it makes his character appear more "magey" to him. Personally, I think the fact that a mage's physical stats are significantly lower than a fighter's is quite sufficient.

2) He wants to be able to optimize his point allocation. I would too if we were allowed to, however, since the stats are fixed and there is no opportunity cost to having them the way they are, I don't see an issue. If they released 1.19b with manual stat allocation tomorrow, it would also greatly buff everyone sensible enough to not gimp themselves, which would cause balancing issues.

3) His materia point is probably more valid. It seems like mages especially suffer from extremely materia focused itemization. Generally the +stats from materia are far greater than the bonus stats on equipment, so anyone looking to increase pretty much anything other than raw damage/armor will greatly, perhaps too much so, benefit from using materia.
