What is ESL One?
ESL One Battlefield 4 2015 comes with a few system changes as well - we’ve made a few alterations to the cup and group stages for each season. Each season will now feature five cups each with 16 teams facing off against each other. Every cup will last a day, with the top 12 teams after the five cups making it to the group stage. The group stage will be split up into three groups of four teams, with two teams making it out of each group to qualify for the season finals. These teams will be joined by a team from America and a team from Oceania at the season finals, and will fight it out for the prestigious ESL One Battlefield 4 trophy.
