Is there something special about HW gear that makes the ilevel irrelevant when it comes to desynthesis? The Archaeoskin crafting gear is lvl51 i65 but has a <10% desynth rate at desynth level ~85 whereas lvl50 i90 is >60%.

It really throws up problems with levelling as there's a huge gulf where desynthesis levels are unduly low because of this mysterious change in how ilevel relates to desynth level. Does anyone know of a site or calculation that accounts for this change?

Thanks.
