Thoughts on those Baron changes?

They changed Baron's buff recently and I haven't seen any posts talking about it. What do you guys think?

For those who don't know:

Hand of Baron Baron buff bonus ability power increased. Baron buff stats increase more later in the game. Baron buff now buffs caster minions' durability.

Late game Baron buffs should be hugely impactful, allowing a team which takes them to successfully siege those tough inhibitor turrets. It doesn't look like it's doing its job well enough, so we're bumping up the damage it provides as the game goes later (especially ability power), and boosting its minion buffs. Bonus stats INITIAL STATS 25 attack damage and ability power ⇒ 24 attack damage and 40 ability power FINAL STATS 40 attack damage and ability power at 27:30 ⇒ 48 attack damage and 80 ability power at 40:00 Minion buffs A LARGE BUFF-FIX Fixed a bug where bonus attack damage (ex. Hand of Baron's +50 and Banner of Command's +100) wasn't affecting empowered siege minion attacks against structures at all. This is twice as impactful as it sounds, since empowered siege minions deal double damage to turrets. NEWCASTER MINION DURABILITY Empowered caster minions now take 50% less damage from champions BUGFIX Hand of Baron's area-of-effect damage reduction buff on minions now properly reduces damage from Runaan's Hurricane bolts

Personally, I feel like the caster minions taking 50% less damage was a bit too much. I agree with the Bonus Stats changes but I think just 25% damage reduction would've been a good enough initial change. Thoughts?
