Is there any point to play tank?
Tanks: the type of gameplay where you sacrifice damage, to be a meatshield, and help your team with soaking up as much damage as possible, and distrupt the enemy team with cc, or protect your damage dealers,
But the last whisper, black cleaver or yomuus ghostbalde combo shreds your armor to a true dmg reciever lvl.
Not once I had the horrible experience, where i played full tank cho 4k+ hp, 250+ armor/mres... and... Zed...: last whisper, black cleaver + YG. I even builded thornmail, bcs enemy team was full ad, yed a Zed+ cait bursted me out in TWO seconds. On those point i started to think about... are tanks still valiable picks? Whats a tank now when with 2 item you can nullify anyones resistance? Most game where i play tank i feel like a full ap Zyra: press your skills, and run. Or rush in, hope enemy will waste the ults on you, die in a splitsecond, and your job is "done".
Especially, when most champion reworks now are max hp dmg, current hp dmg, true dmg or the combination of these.
Most tanks now build offtank, or just full dmg, and its a more valid build than the original purpose of a tank.
or
even if the other team has a viable magic damage threat.
is just not good. Build AP on him instead, with his long cool downs you pretty much need to win the fight with your first rotation of cool downs.
