I think that the EU should use Esperanto as a language of communication between the countries... Not English.
So do I.
I suppose the complicated Russian grammar is one of the charming things about the language
Russian grammar is not more complicated than any other grammar.
Planned Russian will be still real Russian language with all its declensions and conjugations. But some irregular paradigmas will be replaced by regular ones, EXISTING IN THE SPOKEN LANGUAGE. The irregular verb хотеть will be replaced by a regular желать or something like that.
