Getting very noticeable how bad this is, on Newfoundland, my little guild with 7 active members is managing to get these GQs daily, and even though we only earn a few coins at a time, I have accumulated almost double the coins compared to the other 2 servers, where I am part of 2 much larger guilds, but the Quests are intermittent. These each award over triple what I get on Newf when the quest is completed, due to the larger number of active players, so it is blatantly clear that any Guild who gets these quests regularly has a massive advantage over those who keep missing them.
What a shame the Testing server staff ignored the reports on these.
