Not really… I use Shadowplay’s DVR, and when something neat happens, I commit it to video with a quick keystroke. Then I review the video afterwards and grab the appropriate shot. Trying to catch good ones on the fly is hard.
Case in point! Hyperion Siren went to Oasis and played Shade’s Wingman. Still hopped up on sniper Maya, I wanted to snipe two things on this relatively simple mission: a Sandworm, and a Rabid Stalker. The Sandworm wasn’t too bad, but the Rabid Stalker left a few scars before I got one.
Also, this guy came at me with an Infection. I switched to a Neogenator (overleveled by three clicks over the gun), and a single DoT application still ate through two thirds of the shield before it wore off. Another shield, some on-level thing, or a second application would probably have killed me with that same shot.
