There seems to be guilds which are intentionally benching 10 players each tw for gaming the matchmaking system. This pretty much guarantees a win because of their deeper rosters possesed by each individual members. And everyone gets more rewards after a cycle of 5 tw. For addressing this exploit matchmaking system could give more weight to standard deviation between guilmembers gp's and average gp of a guild. I am no specialist in designing matchmaking algorithms. I am being very generous when I am calling this a strategy. Guild alliances engaging in such practise are big name alliances, which makes it even worse. I am unaware which moderator or dev should be tagged here. I hope this issue gets the attention it deserves.
