I dislike basically all trinkets that do one or many of these things from a design prospective, regardless of how strong they are.
Trinkets with a damage proc. A trinket that procs some damage for me is not satisfying. I want either stats, or a trinket that does something cool, like the archimonde trinkets did for example.
I dislike trinkets that disrupt your rotation, sadly we have quite a few of those right now. Stormcaller, puzzle box, yes it’s a stat trinket, but it has an awful cast time that really breaks the flow of your rotation. Manic grieftorch…
These trinkets are all strong, but they have a very big flaw, they disrupt the flow, and they lock you in place, the worst one is stormcaller by a long shot, because it locks you in place for 10 seconds. It’s unbelievable that they thought it was a good idea. At least manic it’s only 2 seconds, not only that, but it’s also stronger for gods sake!
In short, i like trinkets that proc stats/have stats, or trinkets that do something cool for the rotation, basically a mini tier set for lack of a better word like the archimonde trinkets.
