I'm lucky to get one piece from one whole week of LFR. We're talking 6 (MSV) + 6 (HoF) + 4 (ToES) = 16 bosses.
Yeah, I did the 2nd half of HoF and ToES last night and got nothing but gold last night.
Even used a Coin on water boss in ToES in an attempt to get the gun. No luck.
Anywho, my thoughts on ToES LFR:
Protectors: Not a hard fight. Killed them one at a time. Basically, just focus them down, kill Orb if it appears, and move out of the storm.
Tsulong: No joke, this fight confused me at first with the different phases. The Night phase is basically just DPS while staying out of shit and moving into the light every once in a while. The Day phase is kinda like the Dreamwalker fight in ICC, where you have to heal the boss. Very important to spread out and have people kill the small adds that spawn, or they'll hit the boss for major damage. (Tank should grab big add and put it in front of boss.) Took us a few attempts for people to figure out what to do.
Lei Shi: Not technically a hard fight, but my group had a little trouble with it, as we ran into the enrage timer the first time around.
Kill only ONE guardian when they pop up, and AoE around if she Hides. If you pay attention, it's really not hard.
Sha of Fear: Pretty simple surprisingly. Tank stands in the middle to activate the wall, and you just pew pew pew mostly. Some adds pop up, but you'll have to attack 'em from behind. Sometimes you'll get teleported to a pagoda to fight a Crossbowman, and you'll have to kill him. They can hit kinda hard...but you can interrupt one attack, and hide behind pillars for Death Blossom. Grab orbs to keep 'em from restoring health. Kill 'em and you'll get a nice little buff. Other than that, really easy for the most part. Just make sure you're behind the wall to not get hit by Breath of Fear.
Heroic Sha of Fear sounds pretty interesting, as it becomes a slightly different fight at 50%. (Plus, you get a nice little buff should you wipe on Phase 2, making Phase 1 easier to burn through.)
