So the beat down and/or escape plan couldn't start at 10k? Climb to 10k vs 20k saves 5 minutes. Still plenty of time to get a new beer and unload the previous one.
A successful sortie may mean climb, beat down, climb, beat down, climb, beat down, then rtb. A 10k cap just gave you 15 minutes more combat time. Time for an additional climb and beat down.
HONK!
