What the hell did they buy?
The majority of the stuff on the store is pants, not literally ;p
Perhaps bag slots, char` slots etc for every class?
Think most I ever had gems wise was 2k, but I got those given courtesy of MistLeague.
I think I bought two lots of gems way back when I played, to aid in the gathering tools, but tbh appart from that, nothing seemed of use in store to me.
