So, I've been playing around with the Titan-exclusive Exotic The Fabian Strategy. It's a fairly decent weapon, with an Exotic perk that increases rate of fire, stability and handling when enemies are nearby.

There's been some talk of that perk not working properly, as there's no noticeable RoF increase. There's also a video going round you may have seen (from KakhisHD) showing that it does work, but the increase is almost unnoticeable. In the video he shows side by side footage of the weapon fired away from enemies vs near enemies, and the latter reloads first. Just. Barely. By a few frames.

This didn't seem right to me, as I know tgat model of AR fires 1 round every 3 Frames (10/sec). The only way for it to shoot faster would be if it went to 1 round every 2 frames, which you'd definitely notice. There's nothing to explain it emptying a whole magazine just 2-5 frames faster unless it's firing between frames (super unlikely) or has an unnatural firing pattern.

So I tested it. I counted the frames manually. I can confirm with 100% certainty that The Fabian Strategy fires at 3 frames per second even when surrounded by a number of enemies. The rate of fire increase doesn't work.

Tl;Dr - Fabian Strategy perk is broken, don't believe those who tell you otherwise.
