I really don't like a lot of the rumored character-class combinations because I'm a huge lorefag and the majority of them go against the lore for that specific race. Taurens don't believe in the light, as they are specifically a nature worshiping race, and so they shouldn't be capable of hosting paladins or priests. Likewise, Night Elves being able to control fire, frost and arcane magic goes against their strict belief system and disregards a major chunk of their racial history. As far as I'm concerned, this is a giant copout by Blizzard as the only classes combinations that make sense are Human Hunter, Undead Hunter, Orc Mage and Troll Druid (sorta). Adding lore-based quests to explain their decisions is an even further cop out. Regardless, the entire revelation was so Blizzard didn't have to release another Hero Class since Death Knights are horrible. Whatever.

As far as the rest of the expansion is concerned, I'm excited to see how it turns out. I don't like the increased level cap, but I hear they're going to limit it to one level per patch, which could make it extremely annoying or decent, depending on how well they do it. Although, it's Blizzard so it'll probably end up being horrible.

Worgen joining the Alliance is amazing, especially since they are supposed to have two customizable forms. This may effect my faction decisions on whether or not I'll switch over any of my characters as having a Worgen anything will be amazing. Goblins are okay but it depends on what they are allowed to have.

The revamp to Azeroth as a whole and the revisitation is going to make the expansion amazing for a lot of people, myself included. I never got to do anything in vanilla because I started way too late and leveled through BC. Now that I actually get to participate in some of the revamped content, I'm pretty excited. I don't like the idea of flying mounts being allowed in some parts of Azeroth but a lot of people have been complaining about the lack of it so it is understandable that Blizzard would relent from their previous statements of not ever letting that happen.

Thrall will hand over the leadership of the Horde to Garrosh Hellscream, while he serves as a coordinator for both the Horde and Alliance forces in and effort to combat the new threat of the Naga and Black Dragonflight. Without Thrall to keep Garrosh in check, he declares open war on the Alliance. In the political upheaval Cairne Bloodhoof is implicated as a traitor to the Horde and murdered by Garrosh. Cairne's son Baine takes over as the new Tauren chieftan. This could explain why Baine was removed from the game in Patch 3.2.2, you can find more information about this in Ahmo Thunderhorn - replacement for Baine Bloodhoof?
I started jerking off immediately when I read this.
