I was basing it off his post and his times he mentioned in his post.
I came up with the method I was using independently on my own,
we both have a very similar approach.
And Yes both are incredibly Fast Credit and XP earners.
You can't go wrong with any of the Methods presented in this thread.
Some take More manual control, and others like my method, are almost Automatic.
Grind away while you still can, Once it's Patched... the opportunity is gone...
which ever method you choose, figure out your Per Hour XP rate.
then you can decide how long it will take and which Method you want to use.
Based on this Post:
