Kabal knows where I'm coming from.
Yes I know about ATMA, I would kill for it, but there is no Mac version. My point was that without this 3rd party program you are literally forced to use some sort of cheat program or play on Bnet if you ever want to acquire something so simple as Tal set or a "medium" runeword like Delirium. Until recently I could not understand why someone would want one of those character builders or item creators out there. Now I understand the frustration that led to them in the first place.
I am a big user of oSkills, and am quite certain that I am one of the very few people that actually understand their uses ie if you intend to use an oSkill item like Passion, there's no point using it on a Pala or Barb and it's a waste of runes if you don't back up your oSkill with plenty of +All Skills items. A example of this would be a CtA Strafer. By using the life boost from CtA you can afford to pump Dex safe in the knowledge that, even with no points in Vit, you will still have an acceptable lifespan. The problem is that this is impossible to achieve in SP without ATMA or online trading - it's possible that you MIGHT get one or two runes from NM and Hell HF, but the amount of time it would take to find/cube up an Ohm rune makes it unrealistic to say the least. Now extend that to the high end rune words, OK so there's a couple of BotD's out there...but without ATMA your chance of EVER making that runeword is diminished eightfold - first you need to find that Zod on the Character that can use it and then you need to find it when that character is a suitable build. What about Last Wish? It's infinitely more likely that someone will find a Zod than 3 Jah, Sur and Ber needed for that.
SP players, without ATMA or online trading (the way Blizzard designed the game, according to AS), are limited to about 1/3 of all the items in the game.
When I mentioned planning characters I meant it like this. My favourite build is the Palazon - an Amazon designed to make the best use of Passion. I have refined the build, over the last two years or so, to the ideal items, which, in Bnet terms, are not that expensive. In fact the most expensive item, Fortitude, is the latest piece of equipment added to her arsenal and it is quite possible to finish Hell in Eth Rattlecage (I know because I did it). However, this build requires specific items to use Passion - she needs +All Skills items and %dam/AR to demons/undead. Without these items (again almost any armour is good) the build is not mush use because many Hell level monsters regenerate faster than she can damage them (without Fortitude it takes a Palazon a minimum of one hour to clear Hell Cows because they are neither demon or undead). This build can't be made on SP. A similar, weaker, build can be achieved, but not a real, optimized, Palazon. I have never found a Seraph's Hymn on Bnet, either using an 850% MF Sorc or a 300% Trapsin...how am I to find one with a <100% Amazon using a melee weapon? What about if the Hell HF drops me a Gul? Oh goody I can make Principle, yay for me.
I will use the SP trade thread here to achieve what I want, but my point still stands. Remove Bnet and ATMA from the equation and D2 would never have been the best seller it was in the first place and it certainly would not still be on the shelves of EBGames etc.
Dupes on Asia are VERY rare. They do exist, especially Off Ladder, but there are extremely few. Being a comparitively small Realm, almost all the regular players know each other and rumours travel fast. At the end of Season 1 the economy of channel KOR-1 (the Koreans are big traders, almost as big as the Chinese), crashed in less than 36 hours because of a public dupe and the sudden mass influx of duped Ber and Zod runes. Season 2 started about 2 weeks later so it didn't have much effect in the long run and there has ben no such incidence since. All in all, if you trade for a Ber rune on Asia, there is a 90% chance that it is legit (insofar as it was most probably acquired by a bot), rather than the 90% chance it is a dupe you have on other realms. This is reflected in trade values.
