Player versus Player

Now grants 4,000 Strength, Agility, Intellect, or Versatility at rank 1 (was 2,000).
Additional ranks now increase this value by 300 per rank (was 200).
Effects are now reduced by 50% in PvP situations.
Developers’ Note: While additional ranks of Concordance of Legionfall are intended to have a low impact, the trait was overall weaker than it needed to be. With these changes, it provides a stronger up-front benefit, and very slightly more value for Artifact Power spent past the first rank. These changes also result in an overall nerf in PvP.

Artifact Knowledge can now be researched to a maximum level of 40 (was 50).
Developers’ Notes: We raised the Knowledge cap from 40 to 50 very late in the 7.2 PTR cycle, out of an abundance of caution: We wanted to ensure that players of all playstyles, as well as alt characters, would view the Concordance trait as accessible. However, between the additional Artifact Power gains added in 7.2 and others that were hotfixed in after the patch released, we’re now well ahead of that mark. Knowledge 40 now seems more than sufficient for players to reach Concordance, and the prospect of months’ worth of additional Knowledge still left to research makes some players feel like their efforts in the interim aren’t meaningful. Therefore, we’re rolling the cap back to 40.

Deepwind Dunk is now 15 minutes long, and each player killed during Deepwind Dunk awards 5 points.
