in less then a few week the lock out on SCoB will be lifted and be farmable (much the same t1-5 is now) since ilvls are getting increased and the third coil is coming out.
free loot, no lockout,farm for days.

if however you are talking about end game raid content as it progresses, no. not as of yet i dont believe...third coil will have the same lockout that SCoB has now and i dont see it to change anytime soon
