I am very frustrated that you don?t have realistic time limits on goals. I have been playing this game for a long time and have never been able to complete a goal that has a time limit on it because the time limit is unrealistic. Especially for things like the Troll trade. I want to be able to earn the Mystic Research Center but you have to have 70 troll coins to do it. There is no way I can defeat enough monsters and make enough trades to get enough tokens to get the research center in 6 days especially only on 40 Energy that regenerates very slowly. It isn?t possible. To use gems to purchase it, I would have spend over $100 which is absolutely ridiculous. It is the same way with any of the challenges, for example the leprechaun challenge that just ended. I was very close to completing it but could not because of the unrealistic time frame. I am very tired of trying to do these goals and get almost to the end and then it closes before I can finish it. I am about to quit and not play anymore. I think the main problem is that you don?t get enough Energy to complete anything! You only have 40 energy and it takes a long time to replenish. Not only that I can?t have more that 2 workshops etc.. and it takes so long to make materials that the goals cannot be completed in a timely manner without spending a ton of money in gems. I don?t mind $5 here and there but to have to spend over $100 to complete a goal in a timely manner is ludicrous.
