I agree. This is one of the top things I want to see Level Up fix. Well, among other top thingsThe entire 5e skill system is a train wreck.

Worst skill? No, I would put Slight of Hand and Animal Handling below Intimidation, and probably History as well.
I don't think knowledge skills should be like normal skills at all. I think each class and background should list the types of knowledge the character knows or can choose from and they should otherwise work like languages and tools do. You might need to add 2-3 more skills for that to work well, but I don't think they're quite deserving of being first class skills. Not even Arcana.
This came up in our game last night. I was trying to persuade a noble who had been working with criminals that the wisest course of action for both of us would be to work together and exchange information. But because a small part of my persuasion suggested the city guard would find out about a tatoo he had of a criminal organization if I left there without knowing what was going on and able to run interference, the DM called for an intimidation check. I was not intending to intimidate him - I was genuinely explaining a likely consequence of us not working together. But, it got me an intimidation check.
I tried to explain to the DM my intent wasn't to intimidate, and he said the NPC perceived it as intimidating for reasons my PC might not know. OK then, my PC is supposed to act intimidating when not intending to intimidate? Should be a winner of a check.
Fortunately I made the check but it nearly blew the entire negotiation.
I could see that, then possibly use different stats for each check: social interaction (Bluff) = INT mod; social interaction (Persuasion) = CHA mod; social interaction (Intimidate) = STR mod; social interaction (Diplomacy) = WIS mod; etc.I do think however sometimes that Deception (or Bluff), Intimidate and Persuasion (or Diplomacy) should all just be rolled into one social interaction skill.
The reason is that Intimidate will usually make things worse in 75% of the time you try to use it to force someone to do something. If you fail you usually shut down the entire social encounter right then and there, and even if you do succeed, that NPC is probably gonna hate you for quite a while. It's almost always a bad idea unless you're dealing with someone you're ready to fight.
