Balancing Soraka Heal
Yes, the dreaded Soraka nerfs. But it has to happen, she is stupid.
Instead of nerfing the heal/ap ratios/amounts, maybe they should do a Kassadin type nerf, where the person healed receives diminishing returns for a time period, or her heal costs increasingly more mana.
I would go for the first option, so that she can still heal her teammates in fights, but does so over time. This is so she can have a smoother laning phase that's not so oppressive to her enemies. They may even be able to buff the initial heal amount, so that she has to time it correctly (You know, have some thought process into her gamestyle, rather than heal bot).
