In short, I feel that the Flash rune should proc when the Crusader is hit, instead of only when taking damage.
I find myself subconsciously demotivated when seeing a Shield pylon while running a GR with the AoV build. In fact, let me pull off my politeness suit for a moment here - I’ve come to the point where I am beginning to outright fu^%&ng hate Shield Pylons for their Flash-rune-disabling “feature”. I think it sad that a power pylon should adversely affect a run for any class in the game.
A simple adjustment to the way the Flash rune procs would solve the issue.
