Morgana is a strong pick, that even when slapped by the nerf bat, is still worth playing. She can bring a lot to the table in a team comp. Her strengths greatly outbalance her few weaknesses.

PROZ:
CC Immune shield
Long *** bind
AoE CC
High damage with ult
Zhonyas+Flash combo with ult is unstoppable
Tanky
Built in Spell Vamp
Defies physics with her bra
Good farming
Ungankable if played correctly

Cons:
High cooldowns
AD carry like Caitlyn eat her
If she uses Hourglass in the wrong position when ulting, can fail

DO NOT QUESTION.
