I want to comment briefly on the points that have been introduced in Cata and then later came by patches added.
First we had the changed world. Areas that were once dry and desolate (parts of the Barrens, for example), are now green and fertile. Others are by Neltharion (Deathwing's real name, story and so;) totally disfigured) rise. For me as a WoW player of virtually very beginning it was hard to get involved with the altered areas, especially since they partially have a very different order. Previously visited it the Plaguelands so with lvl 50 and older. Now you can already questing with lvl 30-35 there. With me, still create confusion; new players will not notice that.
Then we complained Cata two new races: the worgen and goblins. Both have a very great history beginning. In particular, the worgen is full of goose bumps. The story was implemented perfectly in my eyes. As I have read all previous WoW novels, I dare say that I'm pretty story firmly. Both Neltharion and his relationship with the other dragons as well as the new nations were top-implemented!
The Goblinanfangsgebiet is designed very amusing. So you go for example in a Trike or rescues the party ponies that turn out to be floating tire with Horsehead. It is all in all both worth seeing. Unlike Classic with men such as you will not just somewhere exposed in the middle of nowhere and kills tens of wolves. It really is a red thread that story, which you follow and it's also fun.
Again you have the choice of starting area from lvl 80. Very nice I found the underwater world, but also the battle of Mount Hyjal had something.
All in all, the new worlds very beautiful and harmonious. Personally, I mainly Uldum really liked.
Archaeology was added as a new secondary profession. For me it was always too tedious task, so there is none of my chars over 150 skill it. Therefore, I can not say much about it. However, there is to find nice things: pets, mounts, and epic weapons that look really stylish and can be worn with thanks Transmogrifizierung Lvl 85.
The instances are geohnt short but crisp. Just as New 80s you had its problems in the Inis. Since even had some bosses times the CC-lobe be unsheathed - great! I love tactics! Of course now it looks different again, the instances are durchgerusht only in double quick time. but hey, that was always the case when it approached a new addon.
I particularly found the Dungeon Finder. Now my husband and I no longer had to spend hours looking for other players, but only register, choose your role, wait a few seconds and go. Also we were able to cut down Deathwing himself, without having to connect us a big raiding guild.
I liked the Addon liked. In particular, I now look forward to Pandaria, which appears in almost two weeks :)
