Natus Vincere (Na'Vi) recently performed terribly at the PGL Katowice Majors. They were knocked out in the group stages after losing to G2, Immortals and Fnatic and only managing to win against FlipSid3.
Due to this, Ladislav 'Guardian' Kovács and Denis 'seized'' Kostin have stepped down from the team's active roster and are now placed on a transfer list. They will continue to play with Na'Vi until they are found a new team and the transfer is complete.
Both players have played for the organisation for 4 years. Seized was also the only player who had attended all 11 Majors as part of the same organisation.
