There's not enough activity in WoE, at least on my server, to really worry about that issue anymore. As far as the chances of Coins drop, that's a valid concern. Though, one has to wonder what takes more time when it comes to gathering the pop items, farming for time, killing the NM, etc.Actually, I was talking in regards to Walk of Echoes that anyone can enter lot and steal your items at just about any time...
I guess it all boils down to luck I suppose. I do tend to find Walk of Echos to be enjoyably chaotic fun though.
