I think we just need a complete Champion overhaul. Currently, the majority of them are only a minor annoyance rather than a threatening presence. The combat with them is hardly interesting or engaging, as you just hit them with one weapon, then melt it instantly. Bungie should change their mechanics and either create a set method of disrupting them, or make artifact mods more inclusive. For example: a mod would read Unstoppable Hand Cannons / Sidearms, instead of just unstop Hand Cannon
