This brings us back to the issue that 5e is not 4e.
I threw out some sub-classes and got the response: "But it doesn't do support actions every round."
But the problem is that no class does support every round. A Cleric casts Bless then has to concentrate on it. After that you start throwing damage down range. At least, if you want to be useful you do.
I'm willing to bet that the number of players that are willing to play a pure support class is pretty small. And of those the number that insists on a non-magical support class is even smaller. Most would be perfectly happy to play magical Clerics and Bards.
Combine that with the, admittedly also small, group that dislikes the role-playing that is forced on their own characters by the Warlord* and you should be able to see why it has been delegated to a secondary role, as a sub-class option.
* The Warlord inspires, commands or convinces you to fight harder than you normally would because, obviously, you weren't really trying your hardest.**
** "But that is already in the game!" You say.***
Yes, it is. And it doesn't make any more sense when the Bard does it. Personally I re-flavor their Bardic Inspiration as a magical effect. Why does the Bard's inspiring words help you dodge dragon fire, or resist poison, or hit an orc with a sword... 5 minutes after he inspired me to do better? Why can he only speak inspiring words to people between one and five times a day? No reason! Just because! It makes more sense if it is actually a magical resource that gets drained throughout the day.
Also, just because there are a few things in the game already that don't make sense, doesn't mean we need a whole class dedicated to using nonsensical reasons to accomplish super-human (as in, more than a normal human can do) effects without magic.
*** Yes, I understand nobody actually said this. I was anticipating the argument and answering it.
