Can we talk about grievous wounds? Concerned Soraka player!

As a Soraka and Nami main I'm starting to worry the easy application of grievous wounds is getting out of hand. With the (current) change to morello on PBE to apply grievous wounds at any % of health with no mechanical output required it seems a little much?

I understand the need for there to be a way to lower the sometimes absurd values of healing but at the moment there's no trade-off or input on either side required when it comes to it. The question is just "Does the enemy team have X champion? if yes, every single person on our team should buy the grievous wounds item their champion class has access to" there are almost no conditions where buying grievous wounds is actually a bad choice in that situation as all the items with it attached have very attractive statlines.

I think the lack of decision making or interaction on either team is my main issue with how it currently works. Your only decision is to buy it and the only decision the enemy team has is to wait out the debuff or just stop functioning, the niche of champions that heal a lot in a dedicated capacity is actually incredibly small so the idea that it can just be turned off is infuriating especially when there is a champion (Soraka) who has two abilities entirely dedicated to it.

D'you think with this being the case there is any room to re-add the removal of grievous wounds to Soraka's kit in some way? if hesitant to add it back to her ultimate I think there might be an interesting solution in her Q.

Currently healing an ally while Soraka's Q Heal over Time buff is active causes the ally to recieve the buff at a shorter duration, maybe some adjustment where the rejuvination buff also removes/grants immunity to the grievous wounds debuff for its duration?

This would actually add a level of skill expression to Soraka without completely invalidating the purchase of grievous wounds items, if she is able to land her Q and her entire team is debuffed she has to make a choice as to who she removes grievous wounds from. It adds decision making and actual gameplay around the debuff and even adds interesting synergies. (Someone on my team picked Aatrox, maybe I pick Soraka and attempt to aid his game plan by keeping an eye on him and removing/granting immunity to grievous wounds if I'm able to do so)

Honestly I think this would add an interesting strategic element to her character and be a more interesting solution to the problem than just nerfing grievous wounds, which is not what I'm asking for or even think is necessary. I just want some way of dealing with it in a way that adds gameplay and decision making instead of the current nature of the debuff which is the complete opposite of that.
