Since I searched the net for a Shadow Priest-specific guide to the Brawler's Guild bosses and couldn't find one, I figured I'd start one myself.
Here is my experience with the bosses from a shadow priest perspective. Please feel to add your own. :)
General
Overall, many of these fights are movement intensive, so you absolutely want Body and Soul (run speed boost when you PW:S) and you want to pre-pot just before combat begins. Sometimes it's more important for YOU to get away than it is to slow the boss, so glyph of Mind Flay can also be a good choice.
FDCL is good on movement heavy fights, Mindbender is superior if you can stand in one place and burn or have him tank for a bit. Divine insight is better for "most" bosses because you will be moving a lot and when the boss gets to 20% you probably have a kill anyway.
Make sure you use glyph of Dark Binding so you can toss a PoM or renew on yourself without breaking shadowform.
Also, make sure you have a flask, food buff, and go around the room and get other folks to buff you so you have all buffs. Almost everyone will help you out, especially if you trade them a fort buff.
With that out of the way, some specific strats:
Level 1, Boss 1: Bruce
This guy is a joke. All you have to do is watch his cast bar for "Chomp Chomp Chomp". When you see this cast, step through him or sidestep so you're not right in front of his mouth when it hits (otherwise you die). Other than that, it's stand and burn, doesn't matter what talents or spec you have. This is not a dps race, just don't get chomp'd like a chump and you can't lose.
Extra tips: When you get teleported down, pre-pot before combat. Mind blast him as soon as he spawns, then summon your fiend and fade. This will give you a few extra seconds of burn from a distance.
Level 1, Boss 2: Vian the Volatile
Dot him up and stay out of his melee range and burn from a distance. If he gets close, just PW:S and run away. Doesn't matter what spec you have. Dot him up, and watch for his "Fire Line" ability, which is - you guessed it - a line of fire in front of him that'll kill ya. Side step this when he casts at you. Also, don't get hit by the fireballs and do your best not to let HIM get hit by any (they buff his haste). Not a huge priority as it won't kill you, but it will make your life easier if nobody touches those fireballs.
Extra tips: Prepot, fiend, fade works well. Do not silence him as his melee hits harder than his spells.
Level 1, Boss 3: Goredome
Doesn't matter what spec you have, although FDCL and DI are nice because you will be moving a lot. Your ONLY concern here is to keep him at range because he puts a red circle on the ground and 1 second later, charges at it. If you're in it when he reaches it, you die. You want to be as far from him as possible when he drops the circle so it's easy to move out of.
Extra tips: Prepot of course. Fiend off the bat is good and will buy you some time, FDCL + DI will let you dot and cast on the move. Tendrils will root him and I'd highly recommend it.
Level 1, Boss 4: Dungeon Master Vishas
As with the other bosses so far, there is only 1 ability that can really kill you - and it's called "Heated Pokers" (which buffs his melee attacks). He casts this when he yells, "I will tear the secrets from your flesh!" (or something like that) and you must not let him melee you while he has this on and it lasts about 8 seconds and then runs out. You have a few options for how to avoid this:
1. Silence it during the cast
2. Fiend tank him
3. PW:S and run
4. Psychic Scream
5. Psychic horror (maybe) - can someone confirm this works?
6. Tendrils (maybe) - can someone confirm this works?
If your gear is decent, you should kill him in 2 or 3 heater poker phases. This fight is really not hard. Just keep him at a distance, dot, burn, silence the first heated pokers, save fiend+fade for the second heated poker phase, and use one of the other techniques for the next. If you are still in the fight for a 4th, your silence should be off CD. He doesn't cast it often at all.
Extra tips: Prepot, and keep your eye on his cast bar so you can silence or react to heated pokers. Make sure your sound is turned on, because he yells out when he's casting heated pokers which can be used as another cue. As long as you avoid getting hit while he has pokers on, this fight is very low stress.
Thanks for reading, I will udpate with the next levels as I get some more time. :)
