I just creeped your logs on world of logs and your dps are definitely getting feared way, way too much.
*** DISCLAIMER ***
World of Logs and recount are inaccurate on Sha because you're out of range of logging on the platforms. Data can be extrapolated though. ***
Here's a link to everyone who got feared by Dreadspray (it's the non damaging debuff):http://www.worldoflogs.com/reports/rt-4 ... boss=60999
Now the logs won't show fears unless the logger was on that platform but extrapolating from your 17 attempts, almost all of which were sub two minutes (1 platform), people need to learn the pie dance.
For comparative reference, here is last weeks sloppy 5 wipe then kill for our guild:http://www.worldoflogs.com/reports/skti ... boss=60999
Over those 6 wipes our highest was a healer at 18. Over your 17 your highest is 40+. Serious room for improvement for everyone except your rogue, hunter and you.
Sha of Fear assist trivializes the platform if you understand the mechanics of Dread Spray. Stand in green pie, do stuff for 8 seconds, move to green pie when it changed and then back and forth every 8 seconds.
