The reason why the Catholic Church did not place strong emphasis on reading Scripture is that they viewed it as Jews do, mainly a liturgical text and not as Marcion of Sinope did, who started the whole canon controversy. Marcion upheld the Gnostic teachings that Scriptures were to be used as "proof" texts. In a liturgical religion Scripture is not so much read individually as proclaimed to you and used for your prayer.
It was one of those things that shocked me greatly upon leaving the Watchtower and I began studying to become a philologist: I had no idea what "liturgy" was and why it was so important. It instantly made me realize how stupid and unprepared for Biblical academia I was upon leaving the JWs, and more determined than ever to learn.
JWs don't have a liturgy like the Jews or first century Christians, and of course there is no liturgical calendar. Texts began to be saved and included in the various canons not so much due to Jews or Christians reading straight through them, but because the texts had portions used in proclamation during liturgical acts. If it were not for the Christians copying the liturgical paradigm for their services, the New Testament would have mainly been up in the air for it was largely decided by what was used for the liturgical readings.
You also cannot judge these texts as if they were meant to live in the vacuum that the Witnesses place them in. The Scriptures were meant to be read as liturgy, prayed as liturgy, and never meant to be used divided from liturgy or its liturgical settings.
