I think WOD brings nothing new just like mop. Yet they think we are going to keep paying. I was against mop in the beginning yet bought it for some good features. However they have been slowly destroying wow as we know it. We expect them to bring out team play and some awesome abilities and new classes. Yet they ruin the game with garrion followers and some so called new abilities. I think what wod should bring is
-more team play based on abilities like warlocks in raids summoning a huge summon to hold on a boss
-mage getting arcane form and allowed to suck int power from the people around the raid as we know
-new item types with high risks
-necro mages
-dk having power to summon the old death bosses from grave and put their abilities to use
there are tons of ideas to throw down and good lores to take the story up ahead yet they really are ruining the game we all once loved.
