I only do LFR to get coins for the legendary quest (still not done. Like 8/4 -.-). I only do the 1st part of MSV and the very last one (endless springs?). Would love to get some tier tokens, but I have 0 luck. The LFR's version for Monk t14 looks so much better then normal/heroic.
LFR has netted me some decent gear tho. Have a nice looking Sha-touched staff... and some other LFR gear that has helped me out in Normal mode.
