Ticks on large monsters health bar (aka red/blue/big golem/big wraith/big wolf).
Summoner spells and ult timer indicator on ally champions (somehow a combination of what spectator vision does and what CV used to do).
Being able to see abilities tooltip by clicking on allies/foes this would be very good for new players trying to figure out what an enemy champion does.
I agree with the first point !
Not sure how to feel about your second point, because maybe it's a strategic choice from Riot to let you only know when your allies ults are ready, not sure though. I think it could be cool but as I said it may not be intended.
I don't really agree with your 3rd point, I mean if someone new want to know more about some champs just go in the shop and look at them, or just figuring out what they do and how they work in game. It may even make some new players find way to counter play champs they don't know by themselves.
