If your bothered about ggc.
Big guild 80 plus active - win
Medium guild 30-50 - recruit some more actives but still a win
Small guild - lose, your working 10x as hard for about the same
Small guild 3-4 active out of 10 - leave
Those in 10 man guilds with 3-4 active are wasting their time doing GQ the loop hole where you were getting ggc has been firmly shut for the most part quite a lot of the quests you'd make more ggc selling the component parts of the quest.
I wouldn't dream of spending 107 gems on completing a quest of any description so I hope guild leaders are advising likewise, it's more than enough to buy a noble deed and would be better spent there. pretty sure someone's maths is off at BB also current exchange rate in merchant is 3ggc to 1 gem, so 264/3 is 88 gems to complete a quest.
