I remember on some vanguard activity there was modifiers that mad you use or banned a certain type of weapon. I think this would be a fun way to spice up trials and switch up the meta for a week. Having more than one modifier might end up being annoying but one per week would make things interesting. [u]Some examples[/u]: No snipers, only solar subclasses, no exotic gauntlets, or must use sidearm. Some players might decide not to play because they don't like the modifier that week but others might see "must have bow" and get really excited.
