We feel the largest contributing factor in the reduction to the latency in these hotspots is the fact that Battlegrounds will be ready for release next patch! Yes, that's right, I said next patch, and yes, I said Battlegrounds...plural! The implementation of Battlegrounds will draw players away from towns and into instanced environments designed for either small-scale or epic battles between evenly matched teams (we’ll be sure to get you more information soon about how the instancing works). With many players taking their PvP action into battlegrounds (due to both the fun-factor and the contribution points for completing objectives), we expect that combat in the outdoor world will be of a much more manageable size.
