Mathematically, it's the same sort of resource pool as Paladins. As long as adequate Short Rests are available, and given a normal Adventure Day (which WotC isnmaking any changes to, which makes sense to me based on my experience), then the Monk is just fine.
And that's the problem. Playing a monk (or warlock) requires the following metagame knowledge:
1. I will get the opportunity to take a short rest multiple times during the adventure.
2. The breaks will come frequently enough that I can gauge my resource pool and how close I am to a refill.
3. Said rests will come when I need them to.
That is an awful lot of metagame knowledge to rely on. And I don't like that the rules assume Union mandated breaks be built into every adventure regardless of the plot or situation.
Add on the fact that monks need points to do almost anything, you will find your points at low levels goes by fast. Unless your action is just "punch once or twice" you will be out of di instantly. Most subclass features further dip into that pool. A shadow monk could use pass without trace, sneak up on a foe, FoB them and then use step of the wind to escape and be out of di in two rounds.
They still have a chance to up the DPS and reduce the drain on di so as to allow the monk cool things without emptying in one fight. They also have the chance to make short rests not a mandatory design step but a tool. But I feel we're probably going to have the 2014 PHB with a new cover at this point.
