Do I need to instal the skyre reproccer to get magic to scale? I went from the no dlc skyre mod to the dawnguard skyre mod recently and my magic damage went from great to utter crap. Being ice focused I notcied my slow was also much worse now. I can't figure out why.

No. The ReProccer has nothing to do with scaling. It merely changes certain stats and names of vanilla and mod-added potions, weapons, ammo and ingredients to be uniform with SkyRe.

can you think of any reason ahy my spells have such lower base damage now then?

Are you using any mods that change spells.

Nope. My best guess so far is that spell base damage from the non dlc skyre was higher than the dawn guard one is. I was reading the old read me and it looks like dawn guard skyre got more resistances added on mobs and the starter spells base damage is like ten now. It was like 20 when I had the old one installed and scaled very fast. Now it takes an entire magiacka bar to kill 1 mob where the other let me kill 3 or 4 enemies before running out. The slow also looks like it gets stronger the longer I concentrate it on someone.
