Holmgang is way too strong for how short the CD is and needs to be nerfed.

What I meant was Warrior could not take them all without swap. I can take all Hyperdrives without a swap no problem. That's a difference in content design that has nothing to do with abilities.

That sounds like a huge problem in terms of efficiency since you are not using your abilities and your co-tanks abilities optimally. There is no advantage to using all of your tank CD's on tank busters over invul especially when your tank CD's can be used on auto attacks instead.
