you can kill them before they can get in close enough to fear.

Spaming your follow key works if you do get feared. Follow range is quite big. I guess it's a little hard with a class that only shoots forward. On my priests i just dot them up and fear them off. if they have a trinket i can just fear again Truthfully i just SWP fear and leave them for dead if they are a caster. maybe a mind blast to speed up a warrior of rogue. 4 Renews is pretty OP so you may want to work out a chain heal chain. or a all hands lesser healing wave. I can live through most attacks cause i can drip 4 renews and 4 flash heals in less than 2 seconds. then ust fear and silence.

What damage do shamans have besides ligntning bolt and chain lightning. Try 5 of those fire ball totems. but a few tremors should give you more than enough time to ripe a team apart.
