Absolutely nothing wrong with that, before you start blaming the opponent's strategy, maybe you should stop and think why you guys shot yourselves multiple times and didn't do anything to avoid losing. You played bad.
This tactic involves more risk, it can easily backfire, because it very quickly comes down to one or two shots at the end, miss that and you are dead.
And lol at "cowardish" gameplay and "running like a girl", if you want to win, do everything for the win, do what's best and what's sensible. To win, you must not die, if it takes a hide on the bottom to achieve that, go for it!
