The simple answers are that I don't think arena costs are in any significant way responsible for users leaving the game.
Of course this was never the point and you should know better, after all the times I've accused you of misrepresenting opinions and assuming things that have never been said. We were talking about new users brought in by an app/marketing, not just any user, including current users.
Some arbitrary two year deadline to "complete" an arena
I think we have in fact established that 2 years is a reasonable time, based on actual examples.
there's simply nothing to substantiate that there is a groundswell of people who get frustrated at the cost of building an arena
People who leave the game, don't ofter threaten to do so in advance on the forums, they just stop logging in. However, the one person threatening to leave on the forums did ask explicitly to take his arena with him to a larger country. You should know, since he's one of your best forum buddies.
This is going nowhere, and we could either spend another hundred posts going nowhere without grace, or I can just walk away. I like that option better.
Let's see if you can stick to it. So far, with your last post, just piled up to the number of posts misrepresenting others' opinions.
