I feel like with the new items he has become much stronger than in season 2 but because his ult is not super reliable he kind of struggles late game. By far he is my favorite mid to play but sometimes I feel like I hurt my team by picking him over some other AP mids out there... Any thoughts?

If you have a strong AoE lockdown team, he works very nicely. Apart from that, other burst casters do his job a bit better. He's still very fun and viable though.

ahahahh most fun thin ien gam pwn al oter team wit brand ulti ahhah
