I've found a handy little macro that will stop you from breaking your own traps! Its simple and can be modified depending on your tank.
/cast Distracting Shot (Rank 7);
/stopcasting
Just change the rank accoding to what type of tank you have. I usually use rank 7 for pally's who use their shield to pull and downgrade it to about 5 or 6 for warriors or druids who use a ranged weapon or Feral Faerie Fire. I just don't recommend anything below rank 4 as it is normally surpassed by healer threat and insted of the mob running to the next trap they decide to squish the squishy.
Hope it helps any hunters who find breaking their own traps annoying.
