Just my point of view/past experience of Siege's lack of recall/sacred journey status...
Back in the day, when Siege was crawling with people, this actually made it more fun. How? Well, first, people lived / met everywhere. Not just in towns, near moongates, or other "safe" spots. Several guilds popped up literally in the middle of nowhere - and a few of them roleplayed as highwaymen.
Knowing that all these people were out there, it made sense to use the roads. You really got the experience of wandering around a medieval land, meeting all the assorted citizens - nice, not so nice, and downright weird, as you went along the roads.
Even meeting a red wasn't as simple as "oh, great, now I die, lose everything, and have to walk around for 10 minutes looking for a healer". Most of those highwaymen guilds would surround you, and ask for tribute. If they were pleased with whatever you offered, they would generally let you live.
Some would attack you, kill you, take one or two items, and rez you. None of the dry looting that became the norm more recently. Of course, if you then chose to start ranting at them, you'd die again - but many would argue that was your own doing!
Guilds like TAX, The Blackoak Brigands, Friends of Beasts, The Barefoot Idiots, and many more made the roads and more remote areas of Siege great fun to travel back then. This does, of course, mean there's a niche market just waiting for some very patient guild to fill...!
But, back then, recall and sacred journey would have severely stunted that culture that formed. I know that culture's gone now - but that's down to the small population, caused by dozens of factors.
The simple fact of the matter is, people want to recall (or gate or sacred journey) from point A to point B because they perceive that there is nothing to do between point A and point B. They may be right - but if they never take the long route, they'll never know.
No, this isn't an argument to bring recall/s.j to Siege. It isn't an argument to keep it off, either. I just wanted to share how I'd experienced it, once upon a time. Thanks for reading.
