Upcoming class updates

So I know assassins are due for an update this year but what's next. I feel like supports need love considering very few people want to play that role. Healers are always problematic to balance around so how about them. Or what about battle supports or their lack of relevance at all. I would like to see more supports that can get in the thick of things rather than being purely utility focused. The only ones that come to mind are thresh and Leona. Maybe some new items could bring other champs to fill this role.

Edit- I guess trundle and voli are in this category too but still it's an unloved category.
