Item build paths are one of the biggest reasons i've seen in Silver that leads to defeat
A
will buy
vs a
and finish
before even considering
then wonder why they get dumpstered
A
will build
vs a
before finally realizing hey maybe a
would keep me from dying as much
It gets really irritating to see this and when you tell them so they usually lash out on you like you just told their mother to have an abortion. You people will win more games if you actually learn to change your build path according to what the game requires instead of "I want this item cuz it's purdy"
For example, normally in my Shaco build path I have to decide between BT or Maw to build before the other, if the enemy team has ap champs that are being an issue I go for maw first. If their ap isn't that bothersome or they lack a lot of it I go for BT. If they have more hp stackers than armor I go for bork instead of LW.
Figure out what the game needs instead of what you want

, most others
unless very skillshot-focused enemy, where I start
. After all, in ranked you can usually figure out who you're laning against.
