I'm sure I'm not the only one to express displeasure at how frequent and annoying the adventures pop up in guild quests. For the average player, they are too frequent to allow for proper replacement of expended resources before the next comes along. There is little or no free play time to engage in adventures of our own choosing which could actually benefit our growth.
A prime example is the frequency of Island of the Pirates which gives experience of 2,752 while incurring losses of 549-677 units which yields a mere 4.48 exp gain per unit lost... the lowest ratio in the game.
While this may seen like a low number, track the occurrences of this (or other) adventures and the lost time replenishing resources become staggering.
Also, consider how quickly guild quests need to be done and factor in attempting to do large or lengthy personal adventures to try and level your island. Where are we to get all the time and materials to accomplish all these things? It seems we are being herded into playing the developer's game instead of being able to play our own game, in our own way and at our own discretion.
Yes, leaving the guild is a way to avoid this issue but then, what would be the point of having guild quests as they are now?
I suggest serious rethinking of guild adventures is needed to allow the players more freedom of choice in play instead of always playing catch up.
