Can someone with better theorycrafting than me explain why Paladin/Sorc is so much better than straight Paladin? I can understand at level 20 taking those Sorc levels would be better, but let's say I'm a Vengeance Pally, I think I'm doing better sticking straight Vengeance until at least lvl 11.. If you take Sorc at lvl 7 you're delaying great things like Haste.
On phone so short shrift:
The question is not so much WHY they are better so much as when and at what. Sorc adds lots of defensive and utility even with only small amounts. I've got a Paladin of Devotion 6/Wild Sorc 4 who leans on Sorc for Shield, Quickened Mirror Image, Twin Shield of Faith, and Quickened Web to fulfill his role as party tank/defender. Tides of Chaos is great too for saves, plus he's Lucky. DPR isn't really his job, and if he's going out with only one other PC against a double-Deadly bunch of Hobgoblin Captains and a Warlord, he's happy if he can do 8 points of damage with his sword while the monk does 12 with her bow, as long as Blur/Web + Shield kept him from taking damage in return, at a low cost in SP.
It sounds like you're going for damage output instead, so sorc has little to offer you until after Paladin 11 is online.
Different builds for different roles.
