I suspect that one reason for the general depression expressed by some who have left the game is that the post-merge Istaria is a less pleasant place than the pre-merge version, and that this applies especially to crafters.
Using the lower Kion works as an example, it was pretty. (I could use Summoners' Isle for cobalt as another example) And it had the non-aggro spiders for flavor, as well as the occasional huntress or fyakki charmer for spice, with the gloomy,skeleton-infestedruins right beside it. It was a reasonable run from town, through pleasant scenery.Bronze was just down the road, for armor sockets or to make a basic tool for a young 'uns. There was an active social life there too, which I have commented on elsewhere. Since iron is used for Tier II, III, and IV levels (and back then tier V as well) metal-based crafters spent a LOT of time there.
By extreme contrast, the current iron fields are bleak, barren fields, devoid of almost all scenery except for the skeletons. ONLY iron golems are found there, with no variety whatsoever. As mentioned by many of of the departed, there is no anvil, or nearby bindpoint with an anvil. (That I know of. ) So players will spend even more time there. It successfully captures the feel of a decaying high security prison.
The run is not pretty either.
Platinum fields? Well, about the same, but without the hills or skeletons. Cobalt field? Same, but white. Nickel is a nice enough area, and mithril is OK. But the iron fields are 3 tiers' worth of exposure.
Since the merge, there has been very little visually attractive content. Premerge, for new content, we had the dryad island and its rainbow bridge, the marvel of rebuilt Feladan, and even the Novian machine.
At release, Lesser Aradoth in its entirety was a gem. (And so were and arethe beginner islands, especially Trismus in beta.) The abandoned and ruined buildings in the north, the stairs that go nowhere, the ogre city, the spiral city, ruxus mountain,the school towers, and the racial cities all engendered a sense of wonder. All were attractive, and many were striking.
Postmerge, we have the new bridges to the lava and ice islands, which are very nice. The abandoned island does have a bit of the old charm, and is pleasant. Tandalar's rift area is breath-taking, and the Shepherd's Mountain ice curtains are a pleasant surprise. The lave and ice Islands themselves are not attractive, nor are the guild islands or the tier one island particularly nice.
I am afraid too many people have felt as our guildmistress did after the merge. Shetraveled around,said "This isn't home anymore" and left the game.
So I enter a plea for more attractive design, especially in areas where a lot of time is spent. There is plenty of dark, doom-laden atmosphere now, so more is definitely not needed. New racial buildings and furnishings will be obviousopportunities for eye candy, as will the lair areas. And please dress up the mining areas.
