Idea for a Soraka rework

Hey everyone, It is a well known fact that Soraka right now is pretty strong. I'm not saying she is OP, she simply has a lot of synergy with the new keystone masteries. My problem is, she is far too easy to play to get all this potential and far too frustrating to play against. Her previous rework adressed some of her issues, for example her Q and E, which work better now in my opinion. But the change on her W made her more a heal bot than ever before. I think that there should be more interactivity and counterplay concerning her W. It would be cool if it could be something like the old Karma W (idk if you remember that), where Soraka connects a line between herself and the ally and as long as this line is not being broken (for example by taking too much damage or getting CC'ed) she heals the ally. Of course, the amount she heals would have to be buffed in order for her to not get too weak, but I think this adds a lot of counterplay and new mechanics to the previous "standing in the back of the lane and pressing W all the time while occasionally throwing Q's" Tell me what you think about it
