WC vs BFD

i three box mage/priest/pally (23 atm) started WC at 19 first full clear at 20. i have done all the quests, get around 11 bars a run, and do a run in around 2 hrs. should i keep doin WC or go over to BFD. i haven't done BFD much but i think its a shorter run but looking at wowhead the drops dont make me wana go there.

should i keep doin WC till im 25 or 26 now that i have it down and go to RFK, or go to BFD till 28, 29 then hit rfk?

go to SFK untill lvl 25 or so and then go BFD untill you reach 28-29 and then RFK

not sure if you can do 3-box rfk at 28 tho, mobs are up to 32 and bosses are 33 lvl

also the place with silencing bats 32 lvl will be hard for pally tank
