Rome II Regulation and the lex loci damni rule

Answer the following questions in an essay: What are the virtues of the lex loci damni rule laid down in Article 4(1) of the Rome II Regulation (Regulation (EC) No 864/2007)? In which circumstances will Article 4(3) Rome II allow for the displacement of the lex loci damni rule? Had the common law already provided a satisfactory choice-of-law doctrine for tort cases – or is the new test laid down in Article 4 Rome II to be preferred?
