I support this idea, as I said in the other topics regarding it, considering the massive changes brought by this patch (not only balancing changes, but also the slot system that makes many old builds impossible and the very long time that will now be needed to get new heirlooms) a heirloom reset is in order for people to be able to adjust their builds to the new changes.
I'd take it further and say a stat reset is in order too, retiring to respec now takes ages and as oKiN said, if the skill conversion rate changes, a stat reset is unavoidable, otherwise people who already used it would have the advantage.
When I asked around, the only reason people don't want a reset is because it would allow those who heirloomed overpowered weapons that are now nerfed (barmace/long iron mace/greatswords) to get away with it. The solution is simple, either don't offer respec points for those items, either do another heirlooms/3 theft (this would partially solve some of the retirement system abuse).
