I was in the last bit of the Creature Slaughter Dome's fifth round, when a Badass Pyro Thresher came up and started ripping shit up. I had like four Second Winds until at some point, the Thresher killed me and my FFYL bar literally emptied in one second, leaving me no time to get a Second Wind.
Now, what changed that? Was it the fact that I had four Second Winds in less than a minute or so? Or was the Thresher so close to me that it was melee'ing my bar down?
Aside from this particular situation, what other things could factor into the FFYL timer?
