Ive met many teams that uses that strategy in Ruins, however, i play with a paladin, making it slightly easier.
Ghost wolf is you friend, set totems, go ghost wolf, step back into the starting room.
When hunter comes forward, run out, purge him off, then run back.
The next time, frost shock him, stress him a little, try to follow up with CL.
Keep doing this, run back and forth, purge off the mage too..
Try frost shock-CL.... 1 of them will fuck up at one point or another... And thats your chance to start a fight
