Because morgana support definitely wouldn't overextend the lane at all! And that spell-shield is always going to be useful against an adc! A big part of the meta doesn't revolve around farming or killing, but rather escape: 1) You can't have very much AoE on a support at all, or they'll push the lane and get ganked. 2) Assassins are picked in mid (partially) because they have "flash mobility," which works better in small lanes than "ghost mobility". Meanwhile, in big lanes, "ghost mobility" is generally better. Because if you are going a long distance and you flash while your opponent ghosts, he'll catch up. But not in midl.
