This is a quick note to tell you about something I've observed on the origin/capital worlds. Some "natural" cover points seem to think you're still moving when you drop into them (your charged abilities, like Snipe, will be spontaneously and mysteriously interrupted time and again, and your character may look like it's "twitching" in place). I'm not sure this is exactly what's happening, but it looks like a familiar issue I've seen in the past.
Temporary fix: Get out of the green cover point and hit "Shift-F" to take portable cover in place. You can set it up behind natural cover if you need to.
If you see your channeled "Snipe" getting interrupted, don't try to keep recasting. Just go straight to portable cover. It'll save some time.
Edit: Please note that this is affecting only a handful of specific natural cover points, not all natural cover points. If you find a "bugged" one just take a moment to Shift-F into portable cover in place (or crouch, if you haven't gotten your AC yet).
