I honestly ignore most of the skills in 5e going off of role play instead of rolls. Unless the skill is relevant to combat. If the barbarian explains a brilliant way to scale the tower, damage its supports and knock it down I don't need many rolls if that's a legit sensible plan. Same if the fighter just says sensible, sane, convincing things to a wizard to get the wizard to allow access to their library.

I think half the issue is in 5e the culture is ROLLS not ROLES. Conan would get told "Roll persuasion" instead of just being allowed to have payed attention to the setting and the character he is interacting with and persuading him like a person would. Which is how ADND worked.

I think one of the biggest issues with modern DND is the gamification of role playing. I've had players try to tell me what check they want to roll, instead of telling me what they do and me deciding what they need to roll. If they even need to roll.

Like saying "I want to roll perception for the room?". Nah. Sod off with that. Tell me what you're doing. If you just throw flour around the edges you will just find the secret door because of the breeze, no roll needed. If you run your hands along the walls you might get a roll to see if you can feel the faint breeze. But don't just tell me you want to roll X.

Martial's are a lot better out of combat if skills are largely ignored and they are allowed to role play instead of roll and fuck off for the next 30 minutes if their roll is shit because they have no relevant skills.

I can't stand rolling based DMs. You can say the most sensible thing in the world but if you have a +1 and they set it at an 'easy' DC that's a 40% chance of just failing. Failing common sense sensible action because you have a whopping 4 skills and your ASI's have to stay in CON/STR or CON/DEX + an ASI feat tax for your +10 damage feat.

I really, really hate how Roleplay is shoved aside for rolling and glossing over vast amounts of RP. It's completely fucked up martials and made them dull as shit outside of combat because no matter what you suggest or say or do, if your DM is a rolling DM you might as well just not bother.
