If you dont want it anymore yea, only thing you can do is drop it.
I`m curious about Walk of Echo`s, what are the benefits if any of ignoring every mob in a flux except for the boss? I see so many people make a beeline for the boss and I`m wondering why.
There is a lower limit of participation that aloow/prevent you to get drops, thats related to the experience you earn at the end. Bellow 1000exp or some number around that, you wont receive the drops. Barely over this limit, you get 1 slot drop, and as your exp grow, you unlock all slots in chest, that is 5.
But the minimal exp to unlock all slots normally is low, like around 4000 exp, hardly a dd wont get this, but its hard for suport role jobs like brd and whm. I always must to cast some dia, para, elegy in fodders to make my mule brd earn some exp.
Also, if the flux is crownded, and everyone just zerg the boss and he dies fast, you have a risk of not getting the minimum exp. In that case, fighting the fodders for exp and leaving the coolkids with boss is smarter.
Finally, about quality, its random, dont worry exping more than the limit. I did lots of woe this weekend with some mules, being my main the highest exp in all fluxes, sometimes capping exp (15000), but normally above 10000, and he didnt get more sacks than others mules. Also sacks are the first slot opened, as my brd mule, with the minimum participation, often bellow limit or with just one slot open, still got more sacks than my main. More slots will allow the gear drops though, but most of them have low value, aside flume belt, windbuffet and aceso choker.
There is a kind of proc in woe, once i proced a ! In a fodder, but its rare, and didnt see anything difernt in that fight, not better drops, but my sample is very short, just did once, dont know what was that.
