Trinkets have extra requirements for them to be popped, even when set to always. In the current release version, it'll time them together with Bloodbath and if you don't have BB set to always ... yeah

.
Is all fixed in the upcoming release.
Victory rush isn't beneficial for your DPS to pop it each time when it's available. Impending Victory is an ability you can enable to be used during the rotation. You can force VicRush though by enabling ImpVic/Vicrush and set a very high HP treshold to use it on. It MUST me 99 or less though. It will trigger alot more, but only if you are below 100% health.
