The musician/entertainer aspects of the bard should be a background, not a class. Its a classic to have warrior-poets and spellsinger wizards. This need not be a class at all.
If you want to build a class like the 2E and 3E bard, add this to a rogue/spellslinger combo.
If you want a 1E bard, add this to a ranger/druid.
Of course, this presumes that backgrounds would be somewhat like 2E Kits and actually DO stuff; in this case it might include the ability to weave magic into song (making spells subtle) or give some degree of inspiration.
I do kind of like this idea. But it goes to what a lot of people have said about other classes for 5e as well. The assassin, most notably. That instead of a class it be a "Theme" that any other class could take. And, frankly, for things like bards or assassins, I don't think this is such a bad idea.
The other thing I've seen in other threads that are being repeated here is the "I want more magic in my martial/UI want more martial in my magic" options...again, notably in the Assassin, but I've also seen it applied to Barbarian and Ranger and a couple of others.
Maybe, every class needs to have 3 options: the "more martially oriented" option, the "normal/average/base" class, and the "more magical oriented" option.
Of course, doing this for every possible "class from a first PHB" would bring us into...well...3 times as many classes to choose from. Which I do not believe is realistic. It also would seem to possibly subsum certain "base" classes into other classes....maybe incorporating the "Power Source" thing from 4e (or some version thereof), just as an organizational tool? But it's an interesting thought exercise.
Some examples springing to mind:
Source......Martial...........Base/Hybrid..........Magical
Divine........Paladin..............Cleric................Priest/Healer
Arcane...........................Swordmage..........Mage/Wizard
Primal.......Barbarian..........Shaman.............Warlock
Natural.......Ranger..............Druid................Witch/Sorcerer?
Martial.......Warlord.............Fighter................
Stealth.......Assassin.........Rogue/Thief..........Bard
Or it could just be something like this...with variants for EVERY class...
Martial................Base/Hybrid.........Magical
"Skald"....................Bard............."Minstrel"
Warlord.Cavalier.....Paladin............Cleric
Paladin....................Cleric..............Priest/Healer
Swordmage............Wizard............Sorcerer
Barbarian................Fighter............Swordmage
"Hunter"..................Ranger..........."Warden" or even Druid, itself???
Warlord...................Barbarian........Shaman
"Batman/Avenger"...Assassin.........Shadow-magic Guy/Ninja.
etc. etc.
Then you can have your "Knight in shining armor Warlords" (a more Martial Paladin, none of the "holy" bells and whistles) or your "Barbarian Horde-leading Warlords"...your "Magic-user with a sword" Swordmage and your "Fighter who casts spells" Swordmage...your "berserker crazed warrior" ("more martial fighter") or your whole "primitive culture/Conan guy" (the Barbarian "base" class), etc.
I don't see it happening but it's interesting [to me at least] to think about...
