My problem with the monk and bard as classes is because they are so focused.
But they don't need to be.
Monk = simple warrior.
Through various abilities, this user of sub-optimal weapons (unarmed, staffs, darts, slings, etc) is able to roll with the tricked-out combat engines. Some of them are squishy but fast, some are solid like stone but poor dodgers, some can break down steel doors with a single strike but can barely outrun the elderly. Some are immortal and some are not.
Take every stereotype of the mystical simple warrior and weave each path into a separate talent tree. A character can be all of one type or a mix of several.
Bard = inspiring companion.
It may be the lute-sy traditional D&D bard, it may be the war skald, it may be the inspiring commander, maybe it's a warrior-scholar with a knack for remembering inspiring tales, or it may be 'that guy that screams and scares off half the enemy army'. Different bards contained in different talent trees. And many will take advantage of several different trees to create a character that is inspiring and useful in all of the above (though not as good as the specialists).
There's lots of room once you're willing to let there be.
