No, HP and MP aren't being increased across the board- the differences in HP and MP between the races with the most and the races with the least are being reduced.
That is, Tarutaru will always be last place in terms of HP, and Galka will always be last place in terms of MP, however the gap between the races is lower. Galka are not gaining more HP, nor are Tarus gaining more MP.
Having differences in stats that were so significant that it made you unable to play certain jobs in a game where all jobs were supposed to be playable by everyone was not a good way to have racial differences. There should have been special traits or abilities instead- minor but sometimes handy effects. The primary difference between races is, has been and will be in most games, appearance. You pick a race because you like they way they look, not because they let you play Job X Y% better than someone who picked a different race.The entire point of having the races be different was they were different.
The reason this is being changed now is it has become more of an issue than it was when the level cap was 75. Tarutaru have enough less HP to where they can't play tank jobs in some of the harder content. (While galka were somewhat less adversely affected by having lower MP, it is still a bit of an unfair setup.) Especially since we can't (currently) change our race, it makes sense to reduce the advantages/disadvantages that exist between them.
Bla bla bla bla anyway, races will still have their attributes, just two specific stats won't differ by as great an amount as they used to. It's fine, no harm, no foul, everybody wins.
