These do not seem to take into account Rapture returns, just raw Spirit.
Normally I'd prefer a static Int trinket with Spirit proc(Spirits, Relic) over static Spirit with Int proc(Qin-Xi's). However since Rapture mana returns have been changed to only be affected by Spirit, if you don't get a decent Rapture during a Spirit proc, static Spirit might provide more(stable) mana returns. Remember Rapture was buffed a few weeks ago and there were some indications that multiple procs were also back(intended?).
Has anyone done any theory crafting on the matter or maybe some thoughts?
Multi-rapture was back, but looks like it's gone with the 5.1 patch based on my Elegon parse from this week.
Note that because rapture is on a 12s cd and most trinkets are 15-20s durations, if you can time your use of shield well, you will get a higher return on your spirit than you would see from an averaged amount of spirit.
Say, for example, you have a trinket that provides 3000 spirit for 20s on a 1m cooldown. This averages to 1000 spirit. However, though your trinket is up for only 33% of the time, you can have the buff for 40% of your rapture procs. Also if you get a trinket with a buff duration of 15s, it will be stronger than a trinket of the same item level with a 20s duration, because the spirit buff will be stronger on the 15s trinket. I guess it's not relevant with item choices at the moment, but something to be aware of as long as rapture stays in its current state.
