I've been thinking a lot about any sort of hidden thing I might have missed with these two trinkets ever since I typed up: http://us.battle.net/wow/en/forum/topic/8569110755?page=1#19
After some consideration, I've kind of been rolling around in my mind that the developer intention was for Lightning-Imbued Chalice
to simply outclass the two spirit+proc trinkets because it's from the last boss of the tier and his loot table is bigger.
But I don't understand the logic after they put in the Soothing Talisman of the Shado-Pan Assault
as a valor reward welfare epic. The static int on a welfare epic was going to be a problem, and that logic was validated for me back in firelands with the valor trinket selection:
Raid drops: Eye of Blazing PowerJaws of Defeat
Wellfare epic: Fiery Quintessence
And the Horridon's Last Gasp
is from a much earlier boss and it outclasses both static spirit trinkets if you're putting equal weight on throughput compared to mana regen. So that's kind of the stick in my "progression-oriented" theory for distribution.
Not to mention if my theory is correct that LIC is better than the two spirit trinkets because it's the last boss, then shouldn't the two Heroic versions of the static spirit trinkets be more throughput than the normal version of LIC (after a reforging the spirit)? They aren't more throughput with any of the 5 healers. I really don't understand why the Inscribed Bag of Hydra-Spawn
isn't the valor trinket this tier, and the Soothing Talisman of the Shado-Pan Assault
isn't the Primordius drop.
And even if the bubbles on both Inscribed Bag of Hydra-Spawn
and Stolen Relic of Zuldazar
were doubled in power, they still wouldn't be as throughput-powerful as LIC nor as mana friendly as Horridon's.
At the end of the day, I'm wishing I would have contributed more to the trinkets thread from the ptr forums when these trinkets were being discussed. I didn't put an ounce of mathematical effort into them until they were live.
