The biggest issue of Drunken Master is drinking, the tools he gains when he is drunk are very useful, but the drinking cooldown is pretty bad, since the moment you recover from a drink, you only have 9 seconds to land anything, most of the time, you will end up landing it, when you have 1 to 2 seconds left.
So most of the time, you want to choose between stay drunk to not lose the buffs, or punishing something and lose all the buffs, as result, you end up not doing pretty well, specially when half of your moves last for 3 seconds, taking more of your drinking time away.
And that is if you're are got at doing well with DM, because if you use bf3 after you drink, you will have to drink, because if the opponent stands and apply pressure, you won't be out before your time runs out.
The command grab string is flashy when he is drunk but doesn't grant a drink afterwards, same for db2 meterless.
F2 hits high.
Can't drink in meditate state
The massive juggle window being thigh as hell from different juggles.
These along with the 10 seconds cool down is a lot of risk for such a low reward to gain, imo 10 seconds drunk as cool down its not enough to establish a neutral game based on the tools he has, it should be 20 seconds, since he doesn't lose the buffs if he gets hit.
