You're mad because you got battle points faster than you would've playing out the whole match? I'd love it if all my opponents withdrew on me in a single DT. Stalling and then timing out however...
I don't think time outs in DT is beneficial for you especially when the opponent times out (or even abandons game) in the last (4th) round. you might be getting 35+ points and only end up with 20 with only a benefit of 4 seconds or so. In case of timeouts in the last round you actually lose time and points both.
They should just up the penalty at the 4th round.
Timeouts before then actually shorten the amount of time you would need to win.
