There was this dueling tournament on the classic demo. Looked good on twitch: https://ibb.co/bMEZ5A I got sharded outta there pretty hard: https://ibb.co/jft5Cq
In all seriousness, I think these images summarize the risks with sharding. I can see the benefits of sharding during the first X weeks of launch, however, I see it as a risk to the community if sharding persists. It was pretty disappointing to show up for the tournament and to see the place deserted. To participate in this community event I went to twitch instead of attending in-game.
