In the beginning, it was a small irritant that the wayshrines in Eyevea and the Earth Forge could only be used to port out. The extra step of using a guildhall for transport in was annoying, and it also didn't really fit in the lore of wayshrines as I understand it. Of course, once you'd finished the questlines for the guilds, there wasn't really much reason to visit either location, so it was only a small irritant.
But with Master Writs in the game frequently calling for the sets in these locations, the small irritant has upgraded to, well, "minor nuisance."
I realize this isn't going to be high on anybody's priority list, but I would expect it would take practically no effort to make it happen, and it really just plain doesn't make sense the way it is. So how about removing this minor nuisance, ZOS?
