World Of Warcraft: Big Changes To WoW!

Trade skills are being changed to professions and you will be limited to two per character.
Cooking, herbalism, and first aid are not professions, they will be secondary skills. Survival is not gone, it has been wrapped into Cooking.

Moreover, players will no longer gain skill points but instead invest currency to train skills.

Also, you must have sufficient reputation with a town before you can purchase a mount from them. This makes mounts much more faction-specific.
