That's really the fundamental flaw of Curse of Hubris. If you're using it because you're Mastery-geared and the Crit won't be wasted, you're better served using a Mastery trinket or a Rune of Re-Origination, because the Stamina just isn't very valuable against physical damage, and the trinket's overall value against spell damage is hamstrung by the Crit use, which only has damage reduction value against physical damage.
When dealing with procs from a dps standpoint, treating procs as simply an overall increase worth the proc value times the proc uptime is more or less effective for considering the overall value of a trinket/enchant/etc. Additionally, exceeding autoattack crit cap during a trinket use or proc isn't a major liability for DPS. When considering tankiness, however, estimating procs as average values isn't effective, and we must gear to account for statistical extremes.
For a Warrior, who scales better than us from Stamina, the Crit use is not as bad. This is primarily because while their self-healing pales in comparison to ours, they are efficiently able to turn Crit into spell damage reduction. Druids gain far more for a point of Stamina than we do, and the Crit is not wasted as badly. As such, I see Curse of Hubris not being a Curse of Garbage for the two rage tanks. For the other three, though, what a confused piece of junk.
