My bad using the improper word :P, may be "trend" is more suitable (im not really good at vocabulary). But my main ideas is these 2 mechanics is  just done in some recent rework and nerf/buff/balance : olaf, soraka, kassadin, and rengar are few most recent reworks, get some bonus %-lost-HP healing effect (excluding xerath and MF cause they dont have heal-skill,and excluding gragas too), yasuo,sivir and riven got their shields nerf to the same time length. Just with recently reworked champs, not all of them, if you get my ideas.
