Okay, I know with experimenting the extraction rates of harvestors can increase - mediums can harvest like old large. However, I've heard work that the next patch will revert this - that extraction rates will go back to what they were (experiementation won't matter). Can someone confirm or deny this, preferrably with a link to some kind of post with a SWG dev/csr response. I really need to know if i need to start looking for better extraction rate harvestors or if doing so is just a waste of money at this point. Thanx for any help you can provide.
