Or, I don't know, play a fighter and take a level or two of bard. You gain the specialization without sacrificing much fighting ability.
Yep.
The relevant points in the DMG are pretty simple. If multiple PCs participate in a conversation, the players decide who makes the charisma check. It encourages things like insight during the conversation to figure out what the NPC is thinking. Adding to the conversation grants advantage to the person that makes the check. It specifically states "Create situations where characters who might not otherwise be engaged with a social interaction have to do at least some of the talking." Along with "If a couple of players are dominating the conversation, take a moment now and then to involve the others." A conversation may involve multiple rolls, etc..
If you follow the chart on reactions, during a conversation the worst thing is that you get is "The creature opposes the adventurers’ actions and might take risks to do so." if you get a result of less than 10 with a creature that was already hostile at the start of the social encounter. Last, but not least, bards are less capable in combat because they are supposed to be the skill monkey outside of combat. That doesn't mean the balance is perfect, but if you follow what is actually written in the DMG you still include everyone in social encounters on a regular basis. If one person is dominating every social encounter, the DM is not following the advice in the DMG.
Could the DMG be better? Absolutely. Are people that have 1 person dominate the social aspects of the game while everyone else is mute following the guidance we do have? Absolutely not.
Exactly. So is it REALLY an issue with Fighters? I just dont see it.
This is not me saying there is no gap between mundane/martial and casters. This is me saying a class designed and intended to hit things, is not naturally going to be a good base for
mechanical social encounter resolution.
And WOTC mostly are in their playtest.
Are they dude? Yeah they are throwing some bones here and there, but I'm not really convinced. Granted I dont even care about the social side on my Fighter/Barb characters, so I havent really looked.
I shouldn't have to take barred levels and gain the spell casting that comes with it in order for my barbarian to mimic the archetype of being the chief's son and having some diplomacy powers as well as being a raging brute in battle.
You dont. Noble Background? I dont want to (and would never unless absolutely critical) waste any design time, space, or power, on a Social feature for my class that is from the ground up built to crit things, bigly.
The fight really is between people who want to add new archetypes to D&D and people don't want to add new archetypes to D&D.
Hell, I dont think this is true either. I think its far more likely that any perceived issue is 100% PEBKAC.
I'm pretty sure that near every archetype you like, could be refluffed from an existing class/background/species/feats combination. Especially if we are going to accept things like Aberrant Mind, as a "Psion".
Does that mean a Fighter will be the go to guy for any Social issue that requires a mechanical resolution? Hell no. Should they be that go to in a balanced party that has an established face class? Hell no.
Should a Fighter EVER be better at smooth talking, than a Bard in a purely mechanical/crunch scenario?
