eLife is a journal which say in their policy that they will not encourage impact factor.They now have nearly 10 IF.So do we need IFs to assess the quality of the journal.
Instead of relying on a single measure, a more objective approach would be to view ISI-SCI Impact Factor (Thompson Reuters’ Journal Citation Reports), in addition to other measures - e.g. Scopus-based Impact Factor (SJR). These measures may somewhat differ. However, the increase in an impact factor of a journal could be due to a higher number of self-citations. I would suggest consulting the attached article. Although not specifically devoted to the impact factor it still addresses some of these issues. Hope this might be helpful.

There is a recent Nature piece (the first link below) discussing the drawbacks of the IF, so perhaps something will change indeed. See also the RG discussions at the other links.
You can fiddle the impact factor by citing your own papers, which makes me wonder what the point of IF really is. It is certainly not the quantification of the quality of science on offer.
