I don't know why I am bothering to comment on this subject again, but I do have a few minutes and a full cup of coffee, so here goes:
I have defended TG's need to sell gold and make a profit. I have pointed out that without adequate revenue, TG could not keep the game going for us to play. However, as in any business, you can quickly price yourself out of the market. The seemingly ever increasing gold cost of premium features in this game has already driven many former heavy spenders from the game altogether, and caused others to play with less gold than before. Simply put, higher prices mean fewer sales and fewer customers. Lower prices, of course, mean increased sales and more customers.
When the new build queue was introduced, I took care to use the free final 5 minutes, used the 1 gold finish now and ran the clock down below 2 hours on higher levels to use it. I also used the finish all now when I had long researches as well as buildings without regard to building levels. I spent quite a while testing the feature, and found that I could spend less gold in the long run (I was a heavy gold user, so I usually spent freely). Although doing so meant taking a bit longer to develop the account, I felt it well worth the effort at the time. We did have the option of finish all now for 3 gold at the time. Removing that option was a mistake. If TG just had to do so, increasing the cost to 5 gold would have been a better option than removing it.
I consider some of the negative comments in reference to TG raising gold costs to be at least somewhat unfair, as I have said before. However, reality doesn't mean nearly as much as perception - look at Donald Trump, for example, or for that matter at both he and Hillary Clinton (I will not participate in political discussion here, just using the candidates to demonstrate my point). The perception is that TG is squeezing the players wallets. In the case of the build queue, I have to say that after removing the option to finish all now TG has made that perception appear much more accurate. What is your normal reaction when someone pushes you? Most players are feeling pushed.
If you want to raise the cost to 5 gold, then at least run an open server with that option to test the result, but put it back. TG, you are losing, and the more you try to replace lost players with higher gold costs, the more players you are going to lose.
