Another Post About Tanks

So before anyone says anything about me being salty this isnt a QQ post. Im not really complaining and im not bashing on any champions or those that play them.

Played a game as Volibear support (was playing with some of my friends), it was Volibear (me) and Jinx (my friend) against a Kalista and a Zed support who didnt come to lane all that often.

Kalista built and a , at first i thought we would be fine because she didnt have much AD, but i was wrong. She hit me 2 times with AA's and then a Q, this brought me down to below 30% from around 95% of my life. I went back and bought a and , she came back with a ... So again im thinking well she for sure has no AD and i have both HP and Armor items, well she almost 4 shot me. If she hadn't have missed her Q i would have died from 4 AA's and a Q from 100% life. With only 113 AD... If she wasn't solo laning for most of the game she would have won lane, we couldn't out damage or catch her even though she only had a and a and she was acting like my was nothing, seriously my passive was always gone because 3-4 AA would almost kill me (no she didnt have any armor pen in her runes) the only downfall to this is she would miss out on a lot of kills because she couldnt stack up her E enough to kill me with it.

So what i want to know is why a and is better then a and . Vamp Scepter is 800 gold and Recurve is 900, so 1700 gold spent. Chain is 750 and giants is 1000, so 1750 gold spent. My tank items and her ...damage?... items should have been equal in effectiveness yet hers were clearly dominating mine. She didnt even build AD or Crit and she was chewing through my items.

Idk if this is a problem with Kalista or Tank/ADC Itemization, but i do see this as a problem. I invested just as much gold as her into tank and her investment was making mine look like nothing. Even when i had Sunfire, Randuins, and Thornmail i couldnt 1v1 her because she would chew through me and she only had Shiv for Crit and LW for armor pen (which is enough in most cases...).

So what are your thoughts on the matter? And yes i know Kalista > Volibear because he cant catch her but im talking about her being able to kill me in less then 5 AA's with no AD, Crit, or Armor Pen items. Im not calling Kalista OP either (although she annoys the f*ck out of me sooooooo much omg her passive was driving us all insane...) and im not condemning those her play her, in fact i would like your opinion on this as well.

Proof its not a QQ post: http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1687689306/206176227?tab=builds&participant=5. Support Volibear carry ;D (more like his ult is best for ksing lol)
