i had a bad game... but it proves a point, armor is worthless
so my last game we saw a AD heavy comp and a lux that started
over 
so we knew she wasnt going ap heavy
so i build armor as support
i go

now idk why... but for some reason i thought this would help me surive
i do end up dying quite a lot
about 4 of them becuase i fucked up and about 8 of them were be dying ( and suceeding) to keep another teammate (usally my adc alive) i had a VERY bad game
and i started with me completly forgetting i wasnt lvl 3 and trying to E a
snare
[zombie-brand-facepalm]
( i played like a bronze that game and i admit it, i made stupid mistakes and there is no defense for that) but what id did do correctly was i did itemize correctly, i the vast majority of my deaths won us a fight or kept a person who was more important than me alive.
so whats my point here
well my build is.. i built
and 
i had 188 armor and it didn't do JACK SHIT NOTHING
i was in the process of finishing my
and getting
for more HP
but the point is.
i build correctly i got armor items.. i got HP items i delayed damage to do so i.
and yet i still died to a near full AD comp in less than half a second.
in 2 abilities.
so WHAT IS THE POINT OF BUILDING ARMOR?
WHY would i ever want to lower by damage and build armor he it DOESN'T EVEN DO ANYTHING
i mean if i had 188 MR no magic damage champ in the game could kill me with even a full rotation
and yet with armor it literally makes ZERO DIFFERENCE in how fast i die
there were times where i DIDNT EVEN PRESS ZHOYAS becuase i died so fast.. and i was think, i would wait until i got low enough but i was bursted down so fast i was dead befor ei coudl react
and this wasnt in a teamfight... this was a 1v2 or a 2v2
armor is worthless

is more useful in teamfights than a full tank
? or any tank for that matter? if you are for instance
and are building nothing but tank items then yes your usefulness in teamfights is severely hampered but any tank? they are going to be more useful than most champions in teamfights
but this example isnt a good example.
which i was in the process up upgrading)
had HP and/or Armor.
