I would tend to agree with everyone else, that having portals in multiple locations actually makes the world feel more alive, and having the world feel bigger isn’t really something that needs forced perspective to accomplish (nor is the difference in size really that noticeable, so I’d call it a null point). Also having portals to unique places in different cities is a clear bonus, as it makes all cities viable.
Generally speaking, portals only go to cities, and few capital cities are in an especially convenient location, so it’s not overly convenient to have them.
Because they’re the ones who make them, and they’re unique in that they can make them anywhere, instead of being bound to the will of the developers.
I don’t think anyone was arguing that, and feels a little bit strawman-y. Having multiple locations for fixed portals does not diminish the abilities of mages to teleport, nor does it detract from the ability of mages to make a portal in the middle of out-of-the-way endgame locations (like Argus and the upcoming 8.2 ones) to help out players.
Transmog runs. Dragon Soul’s entrance is in Caverns of Time. So is a large chunk of Cataclysm’s dungeons, as well as the Mount Hyjal raid.
Depends if you have access to Uldir or not. Even with Uldir, there’s still a decent bit of extra travel time added.
I think the latter is. I don’t think you need to keep the Dalaran Crater portal in the new portal room, but it would be nice if it spawned in Legion-Dalaran if you’re on that artifact quest; at least while leveling. It’s a lot of extra time added to an already arduously long level grind to have to travel to some of these spots the old-fashioned way.
You say this a lot, and it reflects the core problem of your argument; you’re leaning a bit on a straw man by taking ‘existing portals’ and making it ‘portals to everywhere’. Nobody is asking for instant transport ‘everywhere’. To get to Stormheim, for example, you need to still fly the old-fashioned way. To get to places in-between capital cities, you still need to spend some time using a mount or flight path.
The existing portal in Legion-Dalaran leading to Wyrmrest is a good example: it takes you to Northrend, but you still have to travel some distance to get to Ulduar, Icecrown, etc. I think there’s benefit in at least having a portal to each expansion, which seems to be the current approach, though I still argue the Caverns of Time are special.
Is the Dark Portal in past Blasted Lands going to still lead to Hellfire Peninsula? The quest flow in Outland is bad enough as is thanks to its age, having to go through Shattrath would be problematic.
