Morgana has the most balanced shield in the game.
If you didn't get it, I was being sarcastic with my title.
I was hard feeding in my last game. 17 deaths. It was a bad lane match-up where I was playing 2v1 voli + cho the whole time. Late game comes and all it took was for me to ask morgana "morgana shield me" to dive balls deep in as Yi, soak up all the CC, delete their ADC to win the game.
The most common excuse I hear people who defend Morgana's shield was "it has a long cd" and "you can bait it out"
Sorry, but that does not work most of the time. Any strong diver is able to win a fight by simply getting shielded, diving to the enemy's carry; then their team has to decide whether to let the carry die and play a 4v5 with their skill rotation off CD or try to save their carry by burning all their CC in hopes one CC goes through and fight a 5v5 without any CC.
I feel out of all the shields, Morgana has the strongest one. Sure Janna's give AD, but in a meta where everyone and their mother has CC, it's every Akali, Katarina, Diana, and Irelia's moist dream.
