Marvel fans are lapping up every single bit of promotion material coming from the makers of Avengers: Infinity War the moment is out. But there also has been constant complaining about the absence of Hawkeye from all of it. The questioning is justified given that in Marvel Cinematic Universe, Hawkeye is one of the founding members of The Avengers. He was the one who provided them with a safer shelter when the rest of them couldn't figure out how they will deal with Ultron. He was also one of the crafty Team Cap member in Captain America: Civil War to secure the services of Ant-Man.
