I realize, of course, that WoW and ESO are very different, but I’m a big fan of how they handle it.
There are no Flight Paths, but there are Shrines. Shrines are less common than Flight Paths, with only a handful per region, but they’re instant travel.
As a result, you spend more time traveling from the shrine to where you want, as compared to a flight path. However, because you got close to where you wanted much much faster, it actually feels more engaging.
I think that’s what I don’t like about removing portals. I don’t mind having to travel a couple of minutes, but I’d much prefer to have a “get close instantly” button, and have to manually travel there.
If you’ve ever ridden in a car in traffic and felt like you could just get out and walk faster (even though traffic is going 25), you’ll know what I mean. It just feels more productive when you have freedom when you travel.
I’ve often thought that WoW could do with some kind of “hearthstone network” where you could pay a hefty fee (100-200 gold) and teleport from an Inn to another Inn.
