pretty much exactly what i said after playing a few games with her, i mastery 5d her the week before the rework.
after the first game it became really obvious how oppressive her new Q was, and i don't see the current changes making any adjustment to that, the increased mana costs as you rank the Q will make it feel like it actually costs mana again but just barely.
yet another nerf to the heal though isn't going to help her play risky, the whole idea of it stealing her health is what keeps her in the back lane.
you will not see good soraka players in the front line making risky plays as long as her heal also hurts her. that alone forces you to spend more time poking and annoying the enemy.
i used her as my main support going back to the AOE Q and the silence/mana heal days, and the most balanced she was was the original version, it had issues mostly to do with the Q's stacking - mag resist and people not really understanding how it was applying.
currently she is a 1 trick pony (q spam) and i dont really think that is actually fun for anyone involved.
