The first is to stop music tourism and restore the old requirement for native language. "Eurovision" was and should be a festival of nations. Enough Anglo-Saxon shows a clock anywhere. With songs of Azerbaijani, Armenian, Georgian, Ukrainian, Greek, Icelandic, etc. would be impossible Russians to represent Armenia, Welsh singer for Cyprus and Swedes to write the lyrics of Norway, Azerbaijan, Spain and many others, counting and receiving support from other countries not because of the quality of the song, but because of the team that introduced her. And when they sing in their native language will somehow bounce from their desire to make themselves of anglo-saxons. For this amendment in the Rules BNT could rely on lobbying and Serbia, Slovakia, Croatia, always sending songs in their native language. And also in the UK, which for years discontents of this universal English-language tune along.
The second change is the countries with bad qualification records in the past 5 years to have chance to qualify easier to the final. This could happen with giving one spot in the Grand final for the best of these group of countries, which hasn't managed to qualify in a certain edition of the contest.
