Wondering about Necro "rotation"

[Infectious]

I have 54 necro. My method is simple. Dark, fear, dot and then send pet. Once mob hits 20% and stops from the dark and send pet off and let dots take the last 20% of hp. If mob still has hp and dots wear off I finish with pet. I use the lvl 30s fear and snare, always splurt first and then eb. If Im low on hp I will throw in lifetap dot. Necro is easy but once your at a spot and take down a couple mobs you will get the technique down to be most mana effcient. I none stop pull at 54 and never go below about 40% mana.
