It's my opinion that +Heal/Shield power needs to be removed.

Currently +Heal/Shield is too binary a stat. It's put on items designed for supports, champions that have heals and shields that do not require mechanical skills to use and thanks to the instant nature of most of them, don't require much tactical skill to use, and keep in mind this is coming from a support main, a support main that dislikes all in supports more than the other types.

Another problem is that AP is still used as a stat for scaling utility moves as well while also granting damage, if someone is going for more utility then it should come at the cost of less damage.

I think that it should be removed and Riot instead introduce a brand new stat for utility scaling and give utility ratios to champions that would be used in such a role. It would also help out with the issue of supports going into a solo lane. If a support wants damage, let them be able to get good ratios for damage but make it come at the cost of utility in the late game.
