The main reason you build GoldPerTenItems and Aura items is because then you have even more money for wards, and more money for bigger items later. Because you wont be getting last hits, you wont have enough money to afford the kind of build you would want. So buy a few GP10s like Heart Of Gold, Kages Pick, etc. Then you can start building for more hybrid items like a Chalice for mregen+mresist, or a Rod of Ages for more AP+HP, or an Abyssal or something for the aura. Depends a lot on the champ, but in general when playing with a full team on a more competative level, youll want to build more on the support end.
