Game Mechanics: Great Divide - "Free" swimming skillups while standing in Thurgadin river.

[Thulghor]

Pretty simple bug. While duoing Shardwurms the other night, we found that, if you sit or stand in the small river/stream that flows from the Thurgadin waterfall south through the zone, and through the Shardwurm caves, you get swimming skillups, even though you're not actually swimming. I would run through it while pulling mobs and I would get swimming skillups. I think Summanus got swimming skill ups just by sitting in it and meditating. Seems like an unintentional benefit of a very shallow stream.
