But farming with W is almost literally the only thing lane Morgana can do. She can't really gank well because she has no mobility and low movement speed; unless nobody pings MIA or wards she can't do anything. She has low kill pressure: is W down? You can't kill anyone, because that's a major chunk of your damage. Is R down? You can't kill someone, because even with Q you can't hold them in a puddle long enough to kill them. Is Q down? You can't kill someone, because even with R they can leave the puddle and leave all your damage. Her only kill pressure comes if you are melee and stay in lane at VERY low health. All lane Morgana brings is a very safe laning phase and extra damage because she has more AP and farm then support morg. What you propose would extremely nerf her laning, which already requires her to get at least 3 points in W to farm.
