funny i thought of that but decided not to post it. But for arena that would be quite annoying. Maybe you just can't pvp or hunt with it.
I have always used my own gear for hunting and I own my epics, but many that I know at all levels can't live without guild gear, whether for hunting or just some epics to boost stam.
Lately I have been using some guild gear for GvG purposes mainly because I can't afford to buy some of the pieces I need, drop rates are sometimes poor at best, and even relatively plentiful gear is a pain to farm on a mobile device. (I know EP, FS wasn't meant for mobile users like me).
I don't see how an increase or a decrease in guild size can really impact how gear is shared that much. Even the smallest of guilds follow this practice.
Modifications may or may not be a good thing, but I think it would take more than that to improve the FS economy.... Drop rates will need to be decreased as well to stimulate demand, I would think. And they are already a bone of contention for some of us.
