I fought agains it a year ago, but I have given up, especially when were we told the player did nothing wrong and as long as you "play the account" you're allowed to invest in your own wonders on your other accounts.
By now the result is that on the dutch server the game went from a stable 14k players to now 36k players.
So you can guess how much this problem is now out of control,(for which I had warned them) there is also no way back (in my opinion) if they decide at some the point to start enfocing the rules everyone just ditches the push accounts. but then harm has already been done. the players who were "allowed"(gedoogd) to push can never ever be surpassed by any new player. In that regard just tell people push all you want might not be the worst idea on the planed.

I agree with the destruction of the FA tournament. not with the tournaments. the effect of skipping quad size research is a much bigger issue, then the wonders themselves. they sure help. but my results were much better results when I had small wonders then today. I'll guess the main advantage is that these days I can finish the tournament in much less time then in the old days where a lot more manual fights where required.
also, I can't imagine anyone be evil enough to block other players advancement by trying to deny them access to these "tradable" new race goods.
even if they did there is always a guild there to help you out.
Even if it would happen and the player is in a guild unable to assist, of if they send me a mail I'll help them out by timing when the goods get at the market so they can get it.
I think this is a case of being a little bit too paranoid.
