Guess I can give a few Brewmaster tips, not much tbh but it could help a few people I guess. This is in no way complete, just some stuff that comes to mind.
Gruul: You can solo soak 2 of the Inferno Slices with a Diffuse and then a Zen Med to let the dps concentrate on burst at the start of the fight. Repeat as needed when your CDs come back up pretty much. Use Celerity to roll to groups easily but you can also Transcendence to/from groups too.
Oregorger: You can happily take 3 stacks of Acid Torrent with a combination of Dampen Harm, Fort Brew, and Zen Med. (Having guard up for each of them of course, maybe not the third but that would be a Zen Med one) This was only because my bear co-tank has no absorbs to reduce mitigate the damage increase from tank damage. Plus, it lined up well with his Phase Change so I take 6 in total in lots of 3.
Blast Furnace: Touch of Death Elementalists and enjoy single target cleaving with ChiEx I guess :v
Hans 'n' Fran: Dampen Harm the Suplex and laugh and laugh and laugh. Also stand between the belts to laugh even more.
Flamebender: Touch of Death the add near the start if possible for MAXIMUM DPS PADDING. Taunting at 2 stacks of the doggie breath worked for us, not exactly a tip but hey others do 3 so I dunno, whatever works.
Kromog: Normally I transcendence the knock-up, as in, I tele back down the instant I get knocked up and then roll back to my co-tank and Touch of Death him out. I use Celerity for this to make it easier. Helps with rolling back from Slams too which is nice.
Beastie Darmac: Not much to be honest outside of having a transcendence at each mount if possible. That and Touch of Deathing adds/spears for MAXIMUM PADDING. Statue is nice for adds if your dps don't stun/slow them in place.
Thomas the Gank Engine: Pretty simple, either watch the fight's addon if you have it or listen to your raid leader. Pad dps with Chi Burst/Touch of Death. Usually set down a transcendence at the designated lane for the split phase.
Iron Maidens: ChiEx to pad those meters but to also make the fight interesting beyond a simple: move out of red, move to red, move to new bombs, move to bomb that exploded marathon fight. (Guard for Marak's Ritual if you have her unless you're in MAXIMUM PADDING mode).
Blackhand: Dampen Harm is pretty damn great tbh, unless of course you're raid plan to sacrifice you to the raid gods during Phase 3 with Diffuse. Nimble Brew + Transcendence the Massive Smashes whenever you can to save a priest grip for your co-tank during Phase 1 and Phase 2. When in the stands/platforms in Phase 2 just Touch of Death + interrupt and jump down. Unless other dps fail to get knocked up of course, then just listen to your raid leader. In Phase 3, you can yolo the Massive Smash with Diffuse/Zen Med into a Transcendence if you're raid want extra time for some no movement dps. (Rip in many peppers)
