For another, you're right, most of the time, the monsters won't do max damage. But, considering the rather large number of attacks the DM makes over the course of a campaign, it WILL come up. And reasonably often.
Think about it. A standard level is about 10 combat encounters and some non-combat encounters. Give or take. 10 combats is about 40 rounds of combat. Figure at least three attacks per round from the baddies (and frequently many, many more) and you've got about 120 attacks per level. That's 6 crits, plus lots and lots of hits.
You are going to do max damage fairly often. Not every fight, nope. But, every few fights it's going to come up. The baddie rolls a pair of crits in a row, the baddies get two full attacks on the fighter without a PC coming up in between. On and on and on.
Fairly often? I've been running giants up against the party for numerous encounters. 2d6+Strength bonus works out to 1 attack in 36 doing max damage... From where I'm sitting, that isn't very often. And if they are using a weapon that does 3d6+Strength bonus, then we're looking at it even less often (1 in 216).
And that's just to get max damage on a single hit, assuming they hit. Add in iterative attacks and the likelihood of doing max damage for the round drops further.
Personally, I'm not that fussed about it.
