Morgana's Black Shield
I don't know what to say about this ability. it's five seconds of total immunity to all cc including knockups. thats the thing that really surprised me, knockups are "hard" cc they are supposed to hit everyone. at 45% cdr and max rank, its 8 second cooldown with 5 second duration with 70% scaling. The magic damage shield thing, at higher ranks its higher than any other shield in the game, but it only shields magic damage so, its balanced. the total immunity to cC thing though, that's fucking amazing.
i love playing morgana as support, but holy crap, she's the only champ in the game who grants absolute immunity to cc for 5 seconds. black shield also seems to cure any existing CC that's happening, as well. she feels way stronger than other shield-based supports.
