I’ve made two posts, that are related to your issue, which I think would greatly help with that. If you agree with them, please comment there, so they get more attention.
A UI that will let you assign “priority” to certain targetable skills, so you can target a specific minion with a skill, even if you are not hovering over them
And a minion outline, which already exists as a functionality in the game, but it’s only when you hover over them with your mouse
