Camate, if they feel an Iridial obi/gorget would be too powerful, you should to remind them the players are iLVL119, not Lv.75 anymore and that equipment is Lv.71/72. I'm pretty sure there are many pieces of gear now that have the combined effects of 8+ pieces of 75 cap gear.

If it is actually a coding issue of forcing only the good weather/day to proc, they would have just told you that instead I would hope.
