Based on search results, "Mobit" is indeed mentioned in the context of the game Rohan Online.

Specifically, Mobit is listed as the creator of the "Rohan Online Leveling Guide" on elitepvpers, a forum often used for guides and information related to online games. Source

Therefore, while not necessarily a "player" in the sense of actively playing the game now, Mobit has demonstrably been involved with Rohan Online.
