The list of teams for the ECS Development League has been updated, with FACEIT announcing that the spot of Natus Vincere will be filled with Epsilon.
Update: First qualifier's runners-up, passions, have been given AGG's spot in the league.
The Development League, created as a stepping stone to the main ECS competition, is set to begin on the 9th of September, with eight teams from Europe and North America competing for the two spots that lead to the promotional playoffs.
When the initial invites were released Natus Vincere were one of the teams on the list, but the Ukrainian organization withdrew from the competition only a few days later. The team to replace them will be Epsilon - whose Joakim "disco doplan" Gidetun recently ended his stint as a stand-in for Ninjas in Pyjamas.
