More changes inc. The constant tweaking around nethershards and sentinax is crazytown.

Rewards from the enemies summoned by Nether Portal Disruptors have been changed: These enemies should now drop significantly more Legionfall War Supplies and Dauntless tokens, but no longer drop Netherchunks or Tier 1 Sentinax beacons.
  • Developers’ notes: We want to make sure that Nether Portal Disruptors and the enemies they attract are lucrative and exciting without overshadowing other options so that players feel inclined to focus only on the Nether Disruptor for Broken Shore play. This should now be a solid extra to add to your activities when it’s available, rather than something to wait around for.
