Florian Le Bihan is a core gameplay designer at DICE, currently working on Battlefield 5. Despite that affiliation, he's also a big fan of Treyarch's new military shooter, Call of Duty: Black Ops 4. Nice, right? It's always great to see competing developers genuinely enjoying each other's work. 

It's not clear exactly why he was banned, but the feeling is that he was just too good to not be cheating. "I guess I hit too many heads :(," he tweeted shortly after becoming aware of the ban. But he wasn't cheating at all: You see, Florian Le Bihan, gameplay designer, is also DRUNKKZ3, a former pro player and manager with the Fnatic esports organization.
