What's the point of building tank now ?

with the new infinity edge :

• The true damage applies life steal, even if the damage is dealt through abilities.

• Without damage modifiers, when critically striking enemy champions with a common basic attack, you deal 30% AD true damage (200% × 0.15) and 170% AD physical damage.

• The true damage stacks multiplicatively with Conqueror rune Conqueror, dealing 32% true damage on crits.

Oh and i forgot about stormrazor :

Total Cost: 3400g +65 Attack Damage +25% Attack Speed UNIQUE Passive: If you haven't attacked in the last 2.5 seconds, your next basic attack will critically strike. UNIQUE Passive: When you critically strike, gain 25% attack speed and 8% movement speed for 1.5 seconds.

In this new meta :

Malphite, Volibear, Maokai , rammus, amumu, alistar, leona, sion, shen, sejuani.... All will be useless against good kiters

oh and against tryndamere and yasuo good luck to escape if he has a stormrazor...

you know riot if you want to make flashier play happens you can just remove unique items like in the past and it will make the same things that you are currently doing to the game ! At least tanks would be able to defend themsleves by stacking 6 sunfire capes...

When Morello left the balance team i knew bad things would happen... He was the guy retaining some mad scientists to implant some crazy ideas and experiments into the game.
