Who is the biggest tank in season 5?

Just buy 6 Warmogs and Elixir of Iron and you'll be huge.

biggest? max stack + size elixir :D

Love me some Volibear!

damage and tankyness that goes to rammus, goes full armor, ult + thornmail + DBC, + sunfire right in the center, hands down no other tank is putting out more damage than rammus

but the best tank to have right now is a tie between sejuani and maokai who just pretty much have the best cc and damage reduction.

Maokai. Been that way sense his rework.Sion CC is to hard to hit with some times and Maokai can give your full team 20% DR for 10sec.

If you mean "who is the strongest tank"? At the moment I'd say Sejuani. She was already decent but the addition of Cinderhulk/Bami's shot her up to God tier, imo.

, while sion gets tanky, he deals next to no damage vs no-afk enemies

or

in my view best ones are

Cinderheimer

The 2 best and most viable top lane tanks in the game right now are maokai vs AP and Sion vs AD.

Best combination of tank and damage is currently . Enjoy it, because it's not going to last.

Most pure tankiness is probably , with his %damage reduction and %health recovery on passive. He is often immortal in the midgame.

I thought for tank's standards Nasus is the strongest damage-wise

I think a fully stacked Cho is still the "biggest".

Being a sion main i would say sion, but in reality maoki is the tank of tanks due to his sustain, however he only becomes that mid to late, vs sion is good early to mid vs
