I wouldn't call those gutting at all. Kindred's kit is too overloaded with ways to keep them topped off during jungle clear and perhaps you'll actually be forced to opt into life steal for sustained fights now. A minuscule heal loss won't hurt her that much. Swain, maybe, but I don't think it's really bad. Swain only really needs to go bird mode during big team fights and the way he works with new ap items like catalyst and his passive, he should be good to keep it up for most of a team fight. He just needs to be more cognisent of upcoming fights so he knows not to use ult just for wave clear.
