That's quite a lot of balance changes here, but the least we can say is that most of the champions that follow absolutely needed to be buffed or nerfed. Overall, in our opinion, and if these changes are ever shipped to the live servers, we can say that Riot Games really nailed it.
You might notice that most of these buffs only affect three-stars champions. That's something, we were expecting for a while already because it never really felt worth to invest in them. Now, it seems just a bit mot interesting.
Three-Star Ability Scaling
"We want to make sure that higher cost three-star Champions are an exciting power up worth the chase of getting them. This is already true for AD/HP scaling champs and Tier 1 Champions, but much less so for others. So, we’re buffing the three-star abilities for some Tier 2 and 3 Champions."

We didn't ask for True Damage Little Legends, but Riot Games delivered anyway — and we can't stress enough how happy we are. These absolutely gorgeous companions will soon join the Convergence, and the least we can say is that we're thrilled by their design!
