The problems in PvE of Holmgang are so niche that's its not an issue and can be easily fixed with a macro.

/merror off
/ac "Holmgang" <t>
/ac "Holmgang" <me>
/micon "Holmgang"

That macro literally solves everything. If you needed to holmgang (outside of tank swaps), it was mostly because things were going badly anyways and its still better than HG where the effect is applied at the end of the animation so you can die popping HG at the wrong time only to be revived and HG is on cd. Holmgang is still the best ivuln in most situations and synergizes with WAR's self sustain. The draw in effect is just a meh bonus that underutilized with every expansion.

My issue is in PvP where the draw-in is physics based and not an instant snap. Anyone who plays WAR in pvp knows what I'm talking about. I just feel a disconnect in any game where momentum based physics exist alongside 0 character collision. Imo they need to make it a bind instead of a heavy if they don't want to fix the momentum based draw-in. The previous version of holmgang used to work like that prior to 6.1.
