What makes Sejuiani so frustrating is that her late game is SO STRONG. Her W/E do such good damage and CC with no damage items. She can also engage from a screen away with Shury's, Q, R.
Sytha, lately I've been building her with the offensive Amumu build:
Philo/HoG
Boots
Giant's Belt
Mercs/Tabi
Sunfire
Abyssal
Sit in team fights and do ridiculous AOE and then Q away when you get low. Fun stuff. The problem is Amumu scales way harder and Nautilus ganks better.
