People need to learn the difference between a need and a luxury..
Just played a game where my LB built Morell and Grail. Still cried she needed blue buff..then later in the game chose to go get blue buff when drag was up and everyone was near it ready to contest..then came to drag with 10% hp.
If you're going to build 40% cdr with a sh*t ton of mana regain. Blue does NOTHING for you. You fking mid laners aren't entitled to have it every time it's up.
In the same game my lucian built PD 2nd. Then started complaining about how tanks are too strong. After which he built a BT and continued complaining.
Before complaining about something try actually doing something to counter it. If a tank is the issue for the adc get a bork get a lw get a yomumu hell get a cleaver. Just because you r%%%%%ed adcs are being babied all game doesn't mean you don't have to at least try to use a brain when playing to win.
This is at least 75% of the issue of why people lose games in bronze/silver. You don't know how to identify when you NEED to do/have something and when it's just a luxury.
Ex. If you're in mid lane and the tower is at 50% hp while drag is up and everyone is going to contest it. That tower is a luxury. Drag is the need at the moment so fuck the tower and go down there. If your team is insanely behind and you can't contest anything then dragon is a luxury. The tower is a need. Take the free objective to help your team get global gold to make their way back into the game.
Learn to learn people. Please.
