Interesting idea using the Founder's Fountain - and that would be a great place to put Guild Stats (if they did that). But in order to keep this as user friendly and intuitive as possible the 'Find Guild' tab would have to be in the user interface. That way the new player would easily discover it and not have to be told to click on the fountain. I had originally proposed a Guild NPC in the lower Harbor - but again the same drawbacks.
We loose most new players right around level 4-6 (unless the harbor npc pass changed that) and this is a crucial time for new players to join a guild for mentoring and guidance.
I agree that the Dev's might be loath to dedicate the resources to this - but as was pointed out - this would help the game enough to pass the ROI and CBA (return on investment / Cost Benefit Analysis).
As far as 'Find Guild' tab name - maybe keep it more immersive - 'Guild Harker' (ok just kidding)!
Otherwise sell us billboard space in Korthos and the Harbor for guild to advert! (ok just kidding)
