The thing is, Fighter isn't a narrative archetype. It's just skill with a weapon, which is also a major part of the class identity for the Paladin and Ranger. And, since multiple attacks is how you represent increased prowess in weapon combat (in Next), it would be really weird if those other classes didn't get any of that.
One way to think about it, that worked well at least up through 3.5, is that classes are all on a spectrum between martial and magical. One one end, you have the Fighter who is purely martial, and on the other end you have the Mage who is purely magical. As you go along the spectrum, you give up more and more of your martial ability in exchange for greater and greater magical ability. The Paladin is mostly a Fighter, but she trades in a little fighting skill for a little healing magic; the Bard is halfway between them, so she trades half of her fighting skill for half of a mage's spells; the Cleric is mostly a spellcaster, so she trades most of her fighting ability for a quite-large amount of magical ability.
The Fighter is Wolverine - the best there is at what he does. That necessitates there being other people who are worse than him, at what he does.
All that is ok for me. I just meant that multiple attacks aren't necessarily the only way to represent being better with weapons, so even if Paladins and Rangers didn't have extra attacks, they still could have other features to make them superior in combat to a non-martial class.
Also, the point of the thread is not to suggest removing Extra Attacks from the game, but only to discuss how it would be if
only Fighters got those Extra Attacks.
From a tactical perspective, making Extra Attacks a unique feature of the Fighter class kind of creates an interesting decision point for the tactical-oriented players, because tactics involving multiple attacks in the same round would require to have levels in Fighter.
From a narrative perspective, multiple attacks naturally suggest fighting speed, not in sheer terms ("I can move my arms faster") but as the result of technique ("I am so long-trained that I need less time to finalize an attack"). Perhaps this is too weak to give the Fighter a narrative edge, but IMHO
technique could be in fact the easiest candidate for the Fighter's narrative concept: the Paladin, Ranger and Barbarian seeing combat as a mean to their causes (whether it is an oath or mere survival), while the Fighter seeing martial prowess as
the cause.
One thing I like about the current setup, is that at least it doesn't go overboard with it (no Cleric or Rogue gets extra attack).
However, at least the special Extra Attacks treatment for multiclassed PC needs to be reviewed... I don't know if I can copy-paste it here, so check it and tell me if you don't also notice something strange!
