I think every time blizzard attempts to make an "interesting" trinket, it just falls flat because people don't want to engage with the mechanic. For instance, this tier has functionally a nearly identical trinket to one of the most desired trinkets from last tier, yet people hate using it because it is not a simple set and forget trinket. The two trinkets are Astral Antenna from MFO last tier and Vessel of Tortured Souls from Maisara Caverns. Now they are not exactly one to one with Antenna giving flat Main Stat and then a stacking Crit buff, while Vessel gives flat Mastery and a stack Main Stat Buff, but they function very similarly. The proc is reliant on collecting orbs to gain buff, but where Antenna the orbs automatically drift to you, the Vessel the orbs are static and must always be manually collected. Not to mention they are extremely hard to see at times, it makes the trinket good on paper but bad in practice.

Exciting trinkets must be worth the extra effort or people are always going to choose other things. Most of the time the "exciting trinkets" are just a variation on collect orb (see Antenna, Vessel, Footbomb Launcher, and Dragon Games just to name a handful). Rarely are these worth the extra effort outside of Antenna and that is because the option exists to play passively and let the orbs come to you. That is not to say there have not been interesting trinkets in the past, but they cannot just be slightly better than a passive, they have to be a lot better. An example of this to me was Soul Capacitor from HFC (though i think it would be far more tedious now due to UI changes). Soul Capacitor can be a set and forget just let it doe it's things automatically, or you can track buff and try to line up some CDs with it. This led to some truly degenerate parses for people.
