Thrash as dps single target priorities as feral dps?
Is thrash included in the single target rotation as a feral druid dps? I've seen videos on feral using thrash everytime it wears off. Should I use it or ?
Yes Thrash does good enough damage to use in a single target rotation. You should not use it like Rake and just refresh it. It's best to use on OOC proc's and if your current Thrash bleed is less then 6 seconds to go. Also if you have 5 combo points and need to refresh Rip soon, but will energy cap then go for it.

Yes trash has a high damage per execute time (hence why clearcasting trash is the best) well as double of shreds damage per energy (used if combo points are not wanted).
