We've done that once in a Clash match...it was funny, but it's obviously an exploit and it's a shame if a team is really relying on it. We won 10000:1000 by the way and half of the other team left. It's not a legit strategy, it's the worst misuse of given opportunities. I'm with the idea of taking out orbs in PvP. The best way to avoid such things is to leave the matchmaking if you see a 5-6man team in the list. I never play against such a team if I'm with randoms.
