Hi,

I'm looking for an add-on that will display or show me somehow what class a person is without having to hover over them or target them.

(Like, if you have health bars floating, maybe it'd say "Druid" above it or something like that)

Looking for something that's easy to use or comes with instructions,

Thanks,

Dosen't exist, also I don't think that this is even possable within current game mechanics.

What about using the class colored nameplates option that is buit into the game. It doesn't get much clearer than that.  You will have to be in range for the nameplates to be visible but there is no way around that for any addon.

I would say, use Gladius, this will add an extra frame to your UI, only when you do arena.

As soon as you or your partner even sees the other team, the frames will popup in the screen with their HP/Class/Mana/Rage all that.
Optionally it'll warn you if a trinket is used and blablabla
