Levelling/farming with Survival.

Post-62 (Steady):-

1. Drop Immolation trap at 20 yards from mob.
2. Jump out to 40.
3. Use Rank 1 Arcane as pull shot.
4. Send pet when mob crosses trap.
5. Fire Serpent Sting macro which contains the desired rank, and /stopcasting.
6. Use steady/auto to kill mob. 2-3 steadies are generally sufficient.

Pre-62.

1. Drop Immolation trap at 20 yards from mob.
2. Jump out to 40.
3. Use Rank 1 Arcane Shot as pull shot.
4. Send pet when mob crosses trap.
5. Fire Serpent Sting macro which contains the desired rank, and /stopcasting.
6. Use straight auto to kill mob.

With Resourcefulness/ToTH this is extremely mana efficient in my experience, moreso if for farming you take Imp Stings rather than Mortal Shots. Sometimes even on my main I'll only use one initial Steady to try and get EW to proc, and then use pure autoshot from there.

Aside from mana efficiency, the single main advantage with this method is that it allows me to barrel the threat wave very effectively. I might go over slightly if I get a crit + trap tick, but I'll go back under almost immediately.
