2 minor issues with Warrior's Holmgang
There are 2 minor issues with Warrior's Holmgang that can happen when they have a target selected for Holmgang. Though there are alternatives to prevent them from happening such as a self-target Holmgang macro or having no enemy target selected when you press Holmgang.
The 1st issue is if you have an enemy target selected and are more than 6 yalms away from that enemy target. Holmgang cannot be activated normally while you both have that enemy target selected and are more than 6 yalms away from that target.
The 2nd issue is when you use Holmgang with an enemy target selected. If the enemy target that was selected for Holmgang dies, the effect of Holmgang ends before it is able to go through its full duration.
These are minor issues and there are workarounds for them. Regardless I see no reason why these issues shouldn't be fixed and it wouldn't hurt anyone if they were fixed.
