This is where the brewmaster to me seem to be doing well (I'm a ~853 iLevel Brewmaster currently clearing out Emerald Nightmare on Heroic):
- Solo Leveling : Perfect
- Solo Elites: No problem
- Solo Elite rares : you die if you havn't got more people with you, just die, you don't have enough dps/cooldowns to keep yourself alive.
- Normal Dungeons : Perfect
- Heroic Dungeons : Great
- Mythic Dungeons : Somewhat ok, we have good speed
- Mythic+ Dungeons : Most of the dungeons fights are about movement and placement and you're good at that, those few sledgehammers that can delete you are few, and you're still somewhat good here, though you're still subpar to the other tanks.
- LFR EN: haha... I wont even comment this is so easy a dead parrot could tank this.
- Normal EN: You're doing okey, some fights you take a beating
- Heroic EN: The bosses with a lot of movement are good, but once you meet the freightrains (Ursoc, Cenarios), you're F'ed you take so much damage no matter what you do, how you do it, and you just get absolutely deleted in a panic situation.
- Mythic EN: I don't know if any Monk tanks are even considered for this,
At some point you'll realize that every other tank is better than you, even at soloing content (you'll find that even the new flavor of the month - the DH is better at taking elite rare mobs - alone), when that realization hits you, you feel like you are failing the team, that you can't do more to perform better, except hope for better gear - and here's the kicker, it doesn't really matter with better gear... - what you say? no.. because you're the most binary of all the tanks, and the result is always "you still take the damage" and that damage still needs to be healed - unlike the DH you can't heal it back yourself and help the healers, unlike the DK you can't just heal yourself, unlike the Druid you don't have Massives of cooldowns and HP, and unlike the Warrior and Paladin (which is so boring btw) you can't just mitigate the hell out of it.
This is of course all my own personal experience and feeling about the class - I really really love my monk, I love that I'm the only monk in town (guild), but I'm also aware that I'm the _only_ monk player I know who plays both Mistweaver and Brewmaster (I hate DPS I'm told that the DPS monk is on top of his game in this expansion, i wish all 3 specs had the same epic feel).
I'm very curious as what the developers think is the "right way" of playing the Brewmaster, I might personally be stuck in the past with some abilities, but that doesn't change the fact that - either it's the other tanks that needs to be re-balanced to be as stressful as the monk, or the monk that needs to be re-balanced to be less stressful is still to be seen.
The monk is stressful to tank, and stressful to heal, stick to dungeons and all will be good, and you'll enjoy the class fully.
