I briefly thought about Keg Brawl, but I failed to actually go and check it out. To clarify, Keg Brawl is one of the various announced capital city diversions, and it was available for play during this past weekend's BWE3. It's pretty much a Capture the Flag variant, just with standardized moves across the board. I found this neat little video on it (via Gamebreaker.tv). Looking forward to playing it for myself come release.
Makes me wonder what it'll yield in terms of rewards. Everything's more fun, if you're getting paid - yeah? Maybe it'll even impact sPvP rank?
