What they should actually do if they were to go down this route, is playtest both way simultaneously and find an averge % faster with the queu and the teleportations that rdf completes in, lets say they (through rigorous testing) find thats about 20%.
Now Double it. Because you should have to give up something to be able to farm etc while having a system do the work for you. You should be trading speed for efficiency.
I would be behind that 100%.
Like ive said a bunch of times in these forums, Manual grouping doesnt provide “social interaction” it provides TEDIUM. which in turn encourages social interaction, in order to avoid all or a portion of said tedium. Having a huge friends list and a bustling guild, being well known respected and liked by the people you’ve played with, IS and SHOULD BE the most efficient route to gearing by a mile.
And unless RDF is heavily penalized, that all goes out the window.
