it could turn very bad without the GE for merchers, i wouldnt mind runescape without a GE as i liked the old methods of trading a lot better, however i use the GE alot to make my cash. Hopefully they can get rid of merch clans for good, i hate them and think that they are useless, i prefer to solo merch
Basicly it was down for a while, whilst they attempted to fix a few problems with friends list, GE and clans etc. Should be back now (working for me)
Tbh you didnt miss alot
