I just kited Syndra and Zac around my turret as Ziggs for a solid 30 seconds
And then finally Syndra flashed into me, ulted, and I died. Because the tower did virtually nothing to help me, and my jungle was occupied at bottom lane.
They didn't land anything. I stopped two of Zac's jumps mid-air with satchel and side-stepped another. Syndra missed every single W and E. There were three total dive attempts in a row, where they briefly dropped tower aggro.
Towers really need to be improved or non-burst casters need to be given some way to deal with being dived, because this is one of the dumbest things I've ever experienced.
