It was announced today, that the Mage tower will be active (no unlock needed) for the rest of the Legion expansion. It havent started yet and no official time is set on when it will start. My personal guess is when pre-patch comes out.
Here is the official announcement: https://us.battle.net/forums/en/wow/topic/20765127414?page=2#38
