On use Trinkets are imbalanced and none exist in PvE where they belong.
I think blizzard is afraid of 2 minute on use trinkets.
They nerfed PvP trinkets saying the burst cooldown stacking is too strong.
Which makes sense.
1 Minute on Use is actually a buff to some classes.
because they can perfectly stack their burst cooldowns with PvP on use trinkets.
For example of 1 minute major burst cooldowns
Rogue // Shadow Dance 1 min
Mage // Frozen Orb 1 min
DK // Pillar of Frost 1 min
Hunter // Beast Within 1 min
Most other DPS classes in Arena have 2 or 3 minute burst cooldowns.
Making the 1 minute PvP trinket less optimal but still strong.
Druids // Incarnation 3 min
Shaman // Ascendance 3 min
Warrior // Avatar 3 min
Paladin // Wings 2 min
Warlock // Demon Soul 2 min
And other classes are unaffected without really have burst cooldowns and can use trinket just for added damage on their normal rotation which include bigger end damage spells as oppose to cooldowns.
I think that lower stats on the Trinkets was probably a good thing.
Because it would create these situations where opening Burst was pretty heavy.
But I think that a middle ground can be found...
For example, if there was a 2 Minute on Use PvP trinket that had no pvp power
But instead offered Mastery or Critial strike like battle master's do.
So a player could chose to have, more consistent damage or more burst damage at the price of pvp power.
Fair? I dunno, it just seems lame how on my Ret paly My pvp trinket got nerfed and it turned out to be a buff for other classes.
I can't even turn to PvE for an on Use trinket since they are none...
I think in a Perfect world.
There would be no on use or on proc PvP trinkets. Just like in Burning Crusade.
You would only use PvP trinket or battle master's.
I think when the human racial came in effect, blizzard was stuck in this awkward position and created new trinkets to compensate
Malevolant Badge of Dominace
2300 PvP power
Pretty much this trinket would be better for PvP then any PvE trinket
Just no Burst cooldown stacking...
Could even buff battle master's to make it compete with this trinket.
