The German squad Ariana Gaming (formerly known as PANZER) have decided to disband amidst roster instability and despite a good run at The Defense.
Citing issues with the motivation of some of its players, a statement released by the Ariana Gaming management confirmed that they have indeed decided to let its team go and that they were 'disappointed with the development of the situation'.
Team manager David Pella offered his take on the issue.

"Team Ariana is no more. You might have heard that the team has not been practicing together for few weeks now. Later on, Leaf decided to leave the team due to some internal reasons. There were no problems with each other and it's basically the skill level that has led to this.
Leaf and Pas would like to improve themselves, while the others didn't want to spend a lot time into gaming. That was the final reason for Ariana to officially drop the team.!"
Even with KuroKy as a stand-in, the team went on to achieve commendable results at tournaments such as Skynet (1st runner's up) as well as The Defense (playoffs). One of its players, Leaf, will continue as a stand-in for Western Wolves.
Roster:
Pascal 'pas' Lohmeier
Burak 'Saga' Seze
Alexander 'Alex-' Reinhardt
Norman 'Leaf' Zörner
