I've never hit 32 and I always plan my builds a few levels beyond that just in case, so it hardly concerns me, but I think it's not so unsensible as it might first sound to let players respec within a certain xp bracket around level 32, 33 etcetera.
Those players are forfeiting equipment stats for character stats and each upgrade is increasingly further away, while for retiring players, each upgrade is increasingly closer, thanks to the xp bonus to higher generations. Retiring players would still get to change their spec more often than non-retiring players, even if it was presented just like that, but strap a high fee on (maybe it reduces an heirloomed item by 1 point to respec, maybe you can't use more than 5k equipment for a week beforehand) and it could be more acceptable to the retiring masses.
