Fate farming problem (PS3)

Anyone else having trouble fate farming on ps3 around level 45+? For me, I can be getting to a fate halfway done and never have a mob pop to attack. It gets kind of frustrating when I can't get a hit in 90% of the time.
Teleporting between to areas farming is painful too when load time are like 40 seconds that enough time for the fate your after to be over. We need longer lasting fates and better ways to filter character and mob that appear on the screen.

Sorry for this pointless rant. I just had to vent somewhere since my gf was getting tired of hearing me scream at the tv. :p
