I, sadly, have to agree with you here. However, one thing that has, in my opinion, always set Blizzard apart from their opponents is excellent customer service (save where hacking is concerned), and an ability to listen to their player base.

I honestly believe that if enough players step up to Blizzard and say "Look, you're basically damning all of us who do not enjoy Arena's and choose not to participate in them to the fiery pits of the Nether, and the last time we checked, this was WORLD of Warcraft not Arena of WarCraft. We pay our money to play, too, and while you seem to be desperate to cater to the casuals, there are those of us who want content we can enjoy and characters that we can enjoy playing, so please, step up Blizz", they will listen. It may take time, but I truly believe in the long term, they will listen.

In my opinion, it is the best thing we can do, as just stating our opinion to other people who believe it at places like WoWInsider and other fan sites isn't going to solve the problem. We need to take it to Blizz's doorstep and say "enough is enough".
