Currently not all trinkets in game work in the way you might expect them to in world of warcraft. I will omit the offensive benefits to trinkets. Firstly, it makes it a lot easier to compare them based purely on their defensive benefit without having to assign a ‘weight’ to how much damage they contribute versus how much damage they prevent. Moreover, in my experience in previous expansions, if I am comfortable with my damage taken such that I can pick trinkets based on how much damage they contribute, I prefer using a DPS trinket anyway, which will of course be significantly stronger for damage done.
Trinket Ranking Overview
Heart of Darkness is quite good compared to trinkets of a similar item level or
lower on single target, though not great unless you have a decent amount of
crit. Recall that ‘single target’ here does not mean the same as for Grotesque
second strongest trinket for Druids is Unstable Arcanocrystal compared to
others at similar item level or lower, if you’re lucky enough to get it, or
strongest where Grotesque Statuette loses out on value.
to trinkets of similar item level or lower, when Grotesque Statuette is
benefitting to its fullest, it’s the strongest trinket for survivability on
average for Druids. Further, its bug with two tanks using it must be borne in mind.
However, it must be remembered that when multiple things are hitting you, its
value dramatically decreases, and generally should not be used if that section
of the fight involves relevant damage.
Darkmoon Deck: Immortality and
Gnomeregan Auto-Blocker 601 are good when the majority of the relevant damage
is mitigateable by armour. They are not necessarily better than the above
options, however. Where the above options get their full potential (such as
when only one thing is hitting you for the Statuette; or when you have a
reasonable amount of crit and there is only one relevant target for the Heart;
or always for the Arcanocrystal), they will outperform it for Guardian Druids.
If you do not have those trinkets, or if it is a situation where they won’t perform
to their full potential, these trinkets will do very well against physical
damage as your next best options. For non-Druids, these trinkets are easily the
strongest by an extremely wide margin.
