In few words in you want to have a chance against enhancement shamans ( as a hunter), you need to:
- Kite perfectly;
- kill the fire elemental totem ASAP;
- time your deterrence with his bursts;
You will see in the video below, that I had like half of my HP and the Shaman was at full HP. I'm also a BM Hunter at the moment, which is the Hunter spec with the lowest DPS at the moment.
Enjoy the video and give tell me what you think :)
