I think that Europe needs to have a central " Eurozone " control with less frequency changes. The current 833.3 Khz VHF frequencies in use are prone to mistuning and " miscopying " by pilots whose first language is not English; add in the various German, French, Italian and Eastern European accents...we have a recipe for disaster. Do like what we have in Central America........cenamer control, etc. It isn't so difficult in a radar environment to have a South/ North/East/West/Central Euro control with less frequency changes. Only snag, some job losses and fewer ATCO bosses to build their own little fiefdoms
