Your assumptions are that AH3 will die unless 'we' fix it and HTC is out of touch with their customers.
Given the general quality of ideas presented and the fact that Hitech reads the forum, plays in the game, and talks to players on the phone and in emails makes me think your assumptions are not supported.
One thing to keep in mind is that nobody knows why so many people DL the game but don't stay, nobody knows why the population is smaller, and nobody knows what to do about it.
People have ideas but anyone pretending to know is kidding themselves.
If you have an idea post it, it may be a good idea. A lot of good ideas have added to the game.
It's a little early for a eulogy. AH2 numbers declined along with the economy. The economy is better now.
Hitech is always working to improve the game. Turn down the drama and have fun playing with your friends.
