Tank runes dont feel like they are even there.
I know this post is opinion based so will most likely be downvoted but here it goes. I feel that unless you have Grasp of the Undying you feel that you don't even have a keystone on. Gaurdians range is super short and then Aftershock (or whatever it is called) is almost impossible to read or see any effect of it. Along with the keystones being less than impressive. I also don't understand why Font of Life rune is so hard to see on an enemy. I figured that when Bond of Stone got replaced by this that they would just use the same rune appearence that was already there. But instead it got turned into this tiny, tiny badge that is hid. Like I said this is just my opinion so will most likely get downvoted. But as a mostly tank player it bums me but I know all the DPS people are stoked.
