If I cannot purchase an item with my current character, I want to know something a bit more specific than "This item cannot be purchased". Tell us what the requirements are. Maybe I'll want to log in a different character who can get it. Maybe I want to plan on getting it as soon as I gain another level. But I don't know that just from such a generic statement.
I do like the fact that we are at least allowed to see items we cannot currently buy with our current character. (That's more than we get in LOTRO.) But for that to be really useful, we would need to know under what conditions the items would become available.
