I've been using my special weapon almost exclusively in battlegounds and the Avalon mission and haven't seen 1 favor of grace. When I switch to my other weapons a favor appropriate to that weapon will drop within a few shots. I've tried void weapons, I've tried solar weapons, I've tried arc weapons and nothing changes. I'm a Titan and I've tried both solar and stasis subclasses. Am I doing something wrong or is this a bug?
