A have a level 10 wizard im messing around with and was thinking, if from 10-20 i add strength, that will give it an extra 30 str points, giving it a boost in HP. Surely the wiz's damage will be just as good, but maybe tank that little bit better with more hp (i know its not a tank, im thinking for PvE uses)
From my experience, a hybird 7:1 seems to be stronger, cause for example, instead of one hit 13k and die, they do 2 hits 10k before dieing. but in somecases, one hit kill would be very useful, and makes you sometimes wish to be full int. you can start with full int, and laters when you get lv60+ to decide if you going to add some str or not, cause then you will know more about what you really want.
