Dark Shadow vs Enveloping Shadows for random BG's

Which yall prefer?

A lot of the time I like enveloping for the survivability (more stuns and health regen from soothing darkness), but sometimes for capture the flag maps where I think i’m gonna need to kill an efc fast I’ll take dark shadow for more burst damage.

Thoughts?

I like Subterfuge Dark Shadow in Randoms lots of times you can force defensives with just subterfuge openers and then come back with a super SD.
