Think of it like this, you'll probably be keeping your hp from 30-50(60)ish, so after the first couple of hits what does it matter if ur hp is 70 or 99? People will probably call u safer if you have a low hp. Personally, even with my logic I like to have a higher hp. Just train range and melee while gaining melee (no sw, pc, cannon) and then train mage by alching.
