This baffles me, because most of the changes also give crit ADs this weird anti-scaling trough where they spike hard on stormrazor and then get relatively weaker until IE is finished, since it's their AD ratios getting buffed. I guess that's the point, but it still feels pretty fucking wonky.
Yeah, it baffles me too, considering all I think they need to do is give each zeal item -5% crit and -200 gold cost.
And the original version of the 
passive that gave the MS on every crit would potentially be worth delaying your build 3200 gold for, but as it is it just makes slotting it in awkward.
Don't worry, It was applied previously the same like Duskblade. They buff champs that used Duskblade while they nerf it.
Sure, why not? Let's buff the Zeal items and buff EVERYONE that uses them.
the caitlyn buff is fckn pathetic this wont fix her problems at all she'll still be trash tier
What's the point of Stormrazor? A crit item without crit chance, doesn't interact with IE, and only delays your build. The only way you can get 100% crit chance is with IE and two zeal items, but what if you play Sivir/Ashe and you want another build?
You can buff crit, but nerf crit dmg. The dmg from crits is the real issue.
You really want Trynd and Yasuo to get more damage?
This isn't inherently a bad thing, buffing Zeal+upgrades is helping via facilitating snowballing which isn't a great move IMO. The problem with Riots changes is that they also buff offences so they do the same thing. IMO the way to help crit carries at the moment would be mass base armour and possibly HP buffs to make it harder to snowball them out of the game as an early bully or an assassin.
