Soraka should be able to self-heal more consistently by hitting Q more easily.
Simple solution: make it necessary to put several points in W for heal and self-heal to be significant, and to put several points in Q to have significant damage, then buff Q's speed and size of the non-slowing part. Spread the gap between rank 1 and rank 5 for both, then make Q easier to hit. This way, support Soraka can pretty much juggle with her HP like one would do with mana, while mid/top Soraka can be pretty much like a Xerath with less damage and some heals.
