It sounds like those one-hit kills on PC right now are gonna slap down most Assaults whether they have 0 or 25 in BAE. The difference is just that it happens a little bit sooner than later...? But if that's the case, you're still missing out on a lot of kills in the meantime.

Really, speed is better for playing an Assault defensively than BAE. It can help you juke, it can get you out of tough spots, make you hard to flank, etc. BAE can only sit there and eventually not be enough.
