wws just is not up to date and accurate for wrath, I have noticed many discrepancies with it personally. I think the layout of wowmeter is nice on the individual level, but the raid as a whole is inferior to wws. When you go to the site, click the language filter in the top right corner.
As far as making a log, you can do it manually, but I find a simple addon, such as Loggerhead(which I use) that will turn a log on or off depending on what zone you are in is much easier. Also, when parsing the logs make sure you Archive(wws) or delete(wowmeter) the current log, as you can only parse 12 hours at a time, and you will have to remember to do this manually before you log in for raids, or go through thousands of lines of text to manually edit out the old logs.
