Blade - had you asked this question last week, I would of pointed you to several threads about using Kingshead, Tormenta and Padres to accomplish the task...
As it is - with the new updates and the loss of several features which to use for levelling Gernades... the question I don't believe can be answered just yet
Players are going to need a few days to figure out taticts and areas which levelling may be possible.
