This would actually make +1 looms far more coveted than they currently are. My fear is that they might start disappearing from the market by people who want to use them for heirlooming, which would leave poor newbs who finally saved up 300K just to have a +1 out of luck. However, with the builds I see most commonly, by the time they save up 300K, they would likely already be level 31.
