Which attribute should I upgrade more?

I’m playing as battle-mage since 2023 (my first char), but I don’t know if I should upgrade my main attribute or health (to keep it balanced, 1-2k+- difference). The reason why I’m asking is because I have 2 battle-mages in my guild that are higher levels than mine. 1st player (2nd pic-MorenaTangela) has main attribute and health balanced and other battle-mage (3rd pic-Dococ) has a 10k+- main attribute difference than health. Any tips?
