INT vs. SPR +math

[weavers]

my mage went full SPR for crits and sp. after cb closed i've been thinking if i should of gone int. i mean at lvl 30 i was criting ~10% of the time with weap, neck(1%) and +spr. and i was doing about 55-60dam with magic missle 1 agaist ice vivi and ~80 agaist bats in the tomb. to solo here i always had to use atleast 1 hp pot.

now if i put +30 into intel my damage vs. bats should of been ~116. considering i put +5 into to spell reduction my dps would of increased a good bit. say if i casted 10 magic missiles with +30int i would do 1160dam. if i was full spr and crit'ed once i would of done 880damage. granted spr full sprt is chance and i could of had 5 crtis in a roll, but more often then not it would of been ~1 in 10.

did anyone go full intell and remember what their damage was around lvl 30 to ice vivi or bats? to confirm my math? now that i'm rethinking things and if they keep int bonus the same it might be better to do a 1:1 ratio of spr to int or 2:1. that or just go full spr and use +int items.

i know spr gives more bang for the buck but once my mage got life tap power wasn't an issue in groups. i most spamed lvl 1 magic missle and fire bolt.(i test lighting and ice bolt and the power ussage and damage increase wasn't very much so i used lvl 1). also would +5damage be worth it for magic missle 1? i only use cool down on it, now i'm thinking of using -CD on firebolt
