Mostly, yes, those are turret buffs. I feel like diving is way too much of an issue, and mid-game it's nearly impossible to defend any of them. The armor shred replacing the Warming Up effect is a way to help champions defend them (by increasing their damage), which I think is a lot better. Overall, these changes are mostly done to make teams think twice before diving, making champions able to answer more adequately to dives, and help alleviate "passive pushing" (minion-only, with Banner and Zz'Rot).

Sadly, I don't have the solution to everything, but after reading your concerns, I should make turrets less sturdy, so that teams should still be able to take them, but keep the damage buffs.
