Req, Req, Req...

The only thing that keeps green items from killing all prices for gold max items.

Have you ever found anything lower than 7 req with max stats?

I've seen 7 req. swords and shields (with mods), but no offhands and wands or bows.

The thing that is killing prices for gold items is the colour of the green items, not their stats. Green is 'unique', gold is only 'rare', so people want green, if they were really just interested in maximum stats they wouldn't have had any qualms using (max stat) collector items before, but either because of ignorance or a self-imposed aesthetic need many insisted on gold equipment instead.

Gold are still better if there isnt a Green item with the stats you want..
