Maybe it's just me or maybe I just don't notice it otherwise but if I play online I can do a couple of BR's and I get the low power warning. I don't think I've taken that many hits or hit the wall that much (no more than I would while offline). Do BR's cause a greater reduction in power online? I wouldn't think so.

I end up absorbing weapons constantly just to power up. For me it's pretty much a last lap/last minute decision to BR while online.
