All classes now have a new talent system which means everyone has had thier talents reset and now will have to use the new talent system to customize thier characters. However most of the old talents have been made into specialized abilities and players will no longer have to go through the annoying process of clicking the screen 50+ times and setting thier charcters up which is good and bad. New Spells are now learned automatically and we will only use class trainers for changing talents, glyphs, class specialization, or to utilize the dual specialization feature.
This also means that most classes and specs are now cookie cutter with jsut a few twists that are selectable on the in game menu at specific levels. More to follow within the specific class guides here on the site.
