First off,
I would like to thank the Warmane staff for offering us a marketplace, and I would like to give some suggestions on how to clean it up and enchance it for some people. As this is a suggestion, it doesn't need to be implemented if the Staff finds this suggestion unfit. This was written with an Icecrown influence, but I can see this being applied to MOP and Cata.
My suggestion is to remove all the items above ilvl 200 and to replace it with items under ilvl 200. Why? Simple, why do the content when you can get it easily just by a collection of 1000 achievement points and a click of a button? With the new marketplace, there is no more need to get into a guild or a pug to do ICC, when in just under a year (depending on Activity Rank) you can get full BiS, without doing anything at all, just a simple click of a button!
Why replace it with items under ilvl 200? It would boost twinking and even the standard population is booming like baby boomers of 1946! After numerous ICCs people may want to sit back and level a twink and maybe use some of their points to buy some gear for them. Over 45% of Warmane's current population (take or less) are twinks. (including all brakets)
That being said, I do indeed hope that this suggestion implemented, not for my sake or any other twinks, but for some 80s who want the WOTLK experience of gearing their gear progressively. As with the current marketplace allowing all items above ilvl 200, what would be the point of dungeons and raids in the WOTLK content area? (Excluding achievement runs, gold farming, lore dungeon quests, etc).
