Wow. The OP has said numerous times that this thread is not about making money it is about the fact that there is very little to buy for lower levels. He is right. When people on the LS are asking if ANYONE has seer gear to sell - and the answer is "no" - so they are just SoL.
Guess what? Seer gear is crafted only. It doesn't matter how much money a person has if no one is selling it. So for crying out loud - stop making this thread about how noobs should just work harder to make money - and talk about the actual issue - or don't bother posting at all.
Numerous times crafters have said it isn't worth their time to make these things because there are not a lot of new players coming in. It is true. There are not a lot of new players coming in. Out of the ones coming in, there will be very few that are going to have enough gil to make higher level players feel like "crafting for low levels is worth their time." Hell, even if every new player was a gil-making machine - it wouldn't matter cause there are not enough of them to keep things moving on the auction house, so likely as not crafters will still feel like it isn't worth their time.
The game is top-heavy. The gear system was designed with a playerbase with more even level spreads in mind. It was designed with the idea that people would be leveling crafts and skilling up by making gear.
So while all of you can say "oh you don't need the gear anyway - level sync in the dunes till you're 30 then leech Abyssea till cap" but that is not an option for new players. And if new players want to make gil they need decent gears so that they won't die while they are trying to do it. Those gears are not available - AT ALL most of the time.
What happens is the lack of gear is contributing to the lack of new players because - honest to god, there are people who quit over the fact they can't find any equipment.
