I accept that Turbine's not really into giving much to rogues (and, frankly, well-built and well-played rogue's don't need much help) but how about throwing us a little bone in the way of Thieves Tools?

The old stack of 50 +5 tools has been around since the beginning of time. With many high level rogues running around with a pack full of epic gear and greensteels, the old tools are a bit mundane.

Have you considered an enchanted or otherwise upgraded tool that doesn't expire with use? It wouldn't be overpowering as even if it was still just +5 (+7) and might save some of us a couple pack spaces. It's more of a flavor item than anything else but fitting for a master rogue.
