While I do agree that implementing something like this would drastically affect Gameforge's sales, there does need to be a change somehow. Not this, of course, but there's hardly any gear in the AH nowadays. No one bothers putting the lower tier gear up, which leaves lowbies stuck with using pre-statted white gear from the AH or quest gear. ABLs need to be on sale more often, or their price needs to go down, just something to encourage sale of a lot of gear.
As it is, it's rare to see things below GC-level weapons on Osha, minus a few exceptions such as the Iron Wheel Great-Axe, and infrequently Fury of the Defenders. Sometimes crafted things are sold, but when it comes to ZS/DL, HoS and RT gear...it's rarely there, except the 4-piece pants/gloves etc sets from RT hard. The shortage of gear is a direct result of a.) ABLs still being expensive, and b.) ABLs rarely going on sale. People do run the lower instances still, pretty often for guildmates, but gear that they end up with just gets trashed or vendored since no one wants to waste ABLs on it.
If nothing else, we need them on sale frequently. Having such large gaps between sales means gear shortages, even for 65+ gear, when there hasn't been a sale on them in a while.
If they didn't keep taking out the lower level shell gear every cap raise, that would be a significant help to lower levels. Getting to 67 isn't terrible. Mobs up to that point aren't all that hard. It's when you get to TB that it becomes impossible to quest if you have no heals, without any gear. And in Merdhin...well, when we get to the point where they remove the 72-75 shell gear, newbies will be absolutely screwed for that zone.
