Why would anyone become proficient with an instrument then when they can instead have the Performance skill? It just isn't coherent.Okay but performance (This is what I'm assuming you are talking about since there is no actual Perform skill) states the following description in the PHB...
Your Charisma(Performance) check determines how well you can delight an audience with music, dance, acting, storytelling, or some other form of entertainment...
This seems to be a more broad skill set than proficiency with one instrument... thus it exists to represent your proficiency with a single instrument. As to which one applies...If he's playing the instrument he's proficient in...it's whichever one the PC wants... However in any other circumstance, including a different instrument or any other type of performance, it's the performance proficiency... it doesn't seem that hard or confusing to me since prof. bonuses don't stack in 5e... is there a situation here I'm not accounting for?
You can take me through an actual example of play where I would ever roll a check using Investigation? I can't. If you look for a physical clue, Perception. If you talk to someone, a social skill. If you research something, the requisite knowledge skill, etc. There is no action you can perform which corresponds to the abstract activity of 'Investigating', its not concrete AT ALL.Oh, I agree with you about the mapping of the Investigation skill, it is a broad based skill... in the same way that Arcana in 4e doesn't map to a specific action... or Perception in 4e and 5e account for numerous ways of noticing things... but again I'm unclear on what the actual issue is. Investigation is broadly defined as noticing clues and making deductions. IMO it's an insight skill for situations or physical objects as opposed to being for people...
When do I use it? When there are clues from which information could be deduced... though I think most players will let you know when they want to use it...
Is it quite clear?? What skill do I use in 4e to deceive someone? How about if I wanted to disable a trap... do I need tools... do they just give me a +2 or can I just use the Thievery skill without them?
In 4e you use Bluff to deceive people, that is QUITE clear. Disabling a trap doesn't REQUIRE tools, again 4e is entirely clear on this. Both in the writeup of thieves tools and the thievery skill it clearly states they grant a +2 bonus. Of course the DM is free to indicate that in some situations they are mandatory, but that would be specific rules for specific situations.
As for knowledge skills in 4e, I don't think there's anything ambiguous about the uses of Arcana at all. Its a knowledge skill which is used whenever a character needs to know some item of arcane knowledge, or when certain specific actions are attempted, or perhaps more generally whenever any action is deemed to depend largely on skill with magic. Likewise with other knowledge skills, though Arcana is usually the one that has the most uses of this sort.
