I am very new to LoL in general, and have found Senna quite fun. What should I build on her? I knew about the BC and DFT interactions, but the new changes have left me quite in the dark. Now I have been going Bloodsong->Shiv->boots->BC->Hexoptics->IB. I belive this build is very far from an optimal one, so what do you suggest? I am really enjoying AD Senna still
