You will still have the legendaries that you got from legion and when you start Battle for Azeroth (BFA), the legendaries will be weaker and weaker for each level up.
The level cap in BFA is 120 and when you are around 118, then your legendaries are more or less totally worthless.
BUT the secondary stats are still good, so keep the legendaries until you get better secondary stats.
