Idea to make Soraka more Managable

I am a Rank 7 Raka main with all but 2 skins on her. So safe to say that I know her very well and being in gold I can say I can play her at a somewhat decent skill level. Her healing is very obnoxious but Riot keeps nerfing her she will be in a state that Sona or Nami have better healing than her. So what if we made her healing the only dependent source of healing. I suggest that every time Soraka heals someone (outside her ult) she then immediately applies grevious wounds to them that last the same duration as her W. This will be affected by CDR too so if she has 45% CDR then the GW would last 45% less as well. This would make trades where the adc uses heal along side Soraka heals more manageable. This would also give the opportunity to buff her a bit as well
