It's been quite the trend for organisations to pick up a 2nd team. Najin e-mFire doesn't want to stay behind by picking up a 2nd team of their own.
Something which is the standard in the starcraft 2 scene is tho have multiple players on a single organisation. This makes it easier to practice and experiment within closed quarters. This way they can develop new and innovative strategies to show off at big events, Surprising their opposition with unseen stuff of who only their teammates know something about.
The League scene is slowly picking up on that aswell, the best example would be MiG Blaze and Frost who both made it to the finals of the OGn Spring tournament. Thanks to their in house training versus eachother, they overcame every team up to the final where they faced one another. Some Western examples are CLG, TSM and Curse who all picked up a brother or "B" team in the past month.
Now onto Najin who'll call their teams Najin Shield and Sword respectively. The former was the original first team which took part in the OGN Spring championships, Yoon "MaknooN" Ha-woonl who you might know from RIOT's world invitationals has been send over to the Sword team to lead them. His replacement will be Gu "Expression" Bon-taek. While the shield team has already qualified for the OGN Summmer championships, the sword team still have to play their online qualifier against "Relive".
On a side note, some of the starcraft 2 fans out there might recognize the coach whole be monitoring both teams. Park "Reach" Jung-suk will be that man who was a former starcraft broodwar player in "KT Rolster".
