The Elder Scrolls Online v5.3.9 includes a couple visual improvements for combat, some stability improvements, and a fix for the Morrowind tutorial. The size of this patch is 120MB.
Tutorial
Fixed an issue where Naryu Virian would fail to start her interrupt tutorial until she moved or the sequence timed out.
General
Using a gap closer ability such as a Charge, Leap, or Teleport will now visually suppress the block visuals during their use. Please note you are still blocking while using these attacks if you were already using block while activating them.
Fixed an issue where the block visual effects could get stuck on your character while using Gamepad Mode.
General
Fixed a crash that could occur during some Justice activities.
Made some improvements that should slightly decrease the amount of crashes and general lag in areas with lots of combat.
