Sorry, but that's not entirely true. Of course getting HP is a really big step into countering the new shreding mechanic, but still you need some defense to counter what's trying to deal with you. Let me explain you with some fast calcs:

·At lv18, with common runes and 9 points in defensive mastery tree, champs commonly have around 2000 HP, 100 armor, and 80 magic resist.

·And now, let's supposed that big-badass lategame Trynd, with a full build, comes out of nowhere ready to rape you, with his 100% crits that with enough AD always deal 1000 damage, 1'76 AS (Which means he's dealing 1760 damage each sec to you) and 40%+24 ArPen.

·To make it worse, some Trynd's fellow is an AD caster has fully stacked TBC on you, so your effective armor is going to be even worse (For obvious reasons, I'm not going to add to this calculations the damage that Trynd's friend has done to our test subject, so let's assume that there's a way to stack TBC without dealing damage, even when there isn't).

·You have an empty slot in your inventory to build something to deal with Trynd. Let's say you go with cheap, all ongoing, Warmog's armor, thus raising your HP to 3000. As your effective armor has been reduced to 21 from 100 [((100*0'75 -TBC-)*(0''6 -% ArPen-))-24 -Base ArPen-] he's dealing 826 damage per hit, 1453 in a sec, divide your HP by that and you'll find out that Warmog's have let you live for roughly 2'1 secs.

·On the other hand, although more expensive, let's say that you invest your last slot into a Randuin's omen, which gives you both 500 HP and 70 armor (2500 HP, 170 armor). Following the same math, your effective armor has been reduced to 52'5, so he deals 655 damage per hit, but now at 1'406 AS due Randuin's antiDPS passive, so the total damage he deals in a sec is of 920. Dividing your 2500 HP by that, you get that Randuin's let you live for 2'8 secs, not far better than Warmog's, but still more efficent.

Now, I'm not saying that tanks shouldn't pack Warmog's (They should even in the previous season). I'm saying that, contrary to popular belief, it's not only HP what counters new shreding mechanics, but also the defenses that are getting shreded, and of course, I'm also saying that passives like Randuin's one help a lot to mitigate some target's damage output. If just Randuin's can counter better some characters than Warmog's, imagine this at a bigger scale.
