Dice has once again updated their Battlefield blog with a bevy of new details. The post is quite verbose but covers many important topics concerning multiplayer such as expanded class roles, field upgrades, suppression and mobility. They are also holding a poll where fans can vote on four of the community-generated Field Upgrade Career Paths and whichever one receives the majority vote will be penned into the game alongside the default variations. Lastly, there is an inclusion of the list of available Specializations players will be able to equip. However Dice states that these are still in a work in progress and will be subject to change over the course of development.
