There's a tremendous amount of very active players out there that just don't visit these forums, I think.
I did 389 PVP matches this week (385 wins and 4 losses) and got an even 1000 trophies this week (for just over 12000 PVP points) and I'm currently ranked 11335 in PVP this week. I find it very hard to believe that all the players ahead of me on the leaderboard are reading these forums, so it's quite hard to reach these players if you have free spots in active guilds. So most of these players will be in guilds that will get them fewer weekly rewards, most likely not knowing they could get far more rewards each week.
But on the positive side: That many active players has to be good for the game (if the servers can handle it of course... )
