ICAO allow in cases where an aircraft is not crossing an international border, they can speak the local lingo. I know this is not the case in France IE AFR and TSC frequently speak French. Unacceptable. As for "Line up and wait" , it's clear, and takes less time to say. When your freq is busy this is an asset, that's why I personally prefer it
