I hope its not you who wrote that on official forum? Because the thing about Wyvern dying or and big gear sacrifices is very inaccurate.
Can we melee? not without giving up on our bubble lasting the full 10min blaze of glory ecliptic attrition, and losing bog ea bubble is going to be a greater dps loss than the geo not melee'ing at all.
You can melee with Idris, AF+3 gloves and JSE+2 neck? Pretty sure JSE+2 neck will keep it alive, but you can also add empy+2 head for master DT and accuracy and pet Regen. Also pet: regen+5 on cape if you want. You also now have Empy+2 feet with high acc and -10%DT.
It's perfectly possible to melee with capped pet DT, 9 pet regen, 10% absorb damage on pet and high master DT. You would sacrifice storeTP for it, but it's not the end of the world for support job. You at least doesn't need to cast anything like melee WHM, you can spend whole time on dps.
