What are the technical issues with Selenium

Limitation of Selenium are as follows -

1.      Very difficult to find good documentation
2.      We cannot run scripts from step as we can do in QTP. SO script generation takes a lot of time
3.      WebDriver doesn’t support safari and mac (as of now).
4.      No documentation for Selenium Grid
5.      Difficult to generate reports.
6.      Password encryption is not possible.
