Without getting into the specifics of the Quests, especially for players who can only play of an evening or a morning ( because of real life i.e. work ) there is 3 things that would make this system of Guild Quests go much more smoothly for a lot of players and they are:
1: Get rid of the tick and let them auto complete.
2: A waiting Quest so we can plan ahead.
3: When a quest requires us to produce something and we are already producing that resource then what we are producing should count from when we receive the quest, not from when we log in.
One complaint for now, is the fact that the cost to complete with gems has risen to a ridiculous level and B.B. will lose out on it, where in the past it was occasionally used I doubt if it will be again.
