It's not a flat out bad trinkets for us, but preferably we would want the spirit one.
also its a trinket that can be used on a lot of fights, so not wasted. mythic wf it helps your throughput a lot.
things like DoC and such is very boosted by this trinket too.
in general you dont want to swap secondaries for spirit, while intellect on the other hand is a roughly equal if not better trade. a 3/3 darkmoon trinket takes you far in terms of regen too.
trinkets is also the cheapest trade for mana to throughput
