Armory and 11.1.7 Belt Limitations
When loading a character using the Armory, the Durable Information Securing Container will default to using the Charged Bolts effect regardless of what your character has actually chosen. This is due to limitations in the data provided by Blizzard when using the Armory API.
The SimulationCraft addon will properly detect and use the choice you have made in-game. Raidbots always recommends using the SimC addon whenever possible.
