Have people not tried actually looking through their inventory and seeing what they can get rid of before they complain, like a proper check. Also people need to realise that the amount of people that 'hoard' items because they have all jobs at 50 is the minority, having all 50s means nothing, most people just level up something and don't bother much with only having 1 gear set which the current inventory space already accommodates for. The people who use up the inventory space like water are in the minority, SE won't see any point in adding extra servers to store that space for something the players should of been managing already.
