My guildies are very disappointed by this system. Every person faced these "contractual battles" willing to leave the game, we already lost 3 top players, and another 4 talking about it right now. The issue is bigger than it seems. I read comments here... Undoubtedly, if the person support such system, he participates in it.
The main problem is that top20 arena became 20vsYou. Of course other players cannot beat the "circle of chosen", because they do not even spend their tries. They have their own schedule of who sits on first place and when, depending on the time zone, and they spend only required number of steps to take first place. Remaining tries are spent to force off newcomers. Good for chosen ones. Bad for all else.
The only way to beat the system, is to make it even more complicated - join another active persons from your top 50 and try to compete with top20/top10/top5 guys, so it would look like Gang vs Gang fight.
Actually, as I see it, nobody cares. People just complain to guildies and leave.
We have guildies which participate in such "agreements" btw. They are happiest persons ever. Always at first places. And I think it is an evidence, that something is wrong.
