In light of the recent success at DreamHack Summer, Finnish player Protosser joins the German team. In turn, MorroW did not extend his contract, leaving him to pursue his career elsewhere.
Mousesports and MorroW were in agreeance not to renew the contract, as the Finnish Zerg, ironically going by the handle Protosser, replaces him in a roster full of promising talents. The Swedish Terran/Zerg, best known for his win at IEM Season V in Cologne and a second place at Assembly in 2011, makes way for the one player who has created probably the biggest splash at the two most recent DreamHack events, Summer and Stockholm. The 18 year-old leaves his old team Fightline, which is responsible for the rise of the players Naama and Satiini, to join up with the likes of up-and-comer MaNa, competitive old-timer HasuObs and German 14 year-old wunderkind Marine.
Jonne “Protosser” Sotala’s statement:
"I’m really happy to join mousesports. They have a lot of very good players and I’ve always had a lot of respect for the team. I’m glad get to be part of it now. They are the first well-known team I enter and I believe they will help me to get better as a player in the future. I will do my best to show great results in the upcoming tournaments and also want to thank mousesports and its sponsors GeIL, Razer, CardCoachess, Thortech, MEDION, Intel & Sansibar for giving me this opportunity."
