What's the point of having 'defined' skills, versus just using attribute checks and giving players proficiency's that they can choose with the GM?
The point of skills is just character differentiation.
But it isn't the only way, in fact the books suggest more than one alternative, and you can always vary the system to your own tastes, if you find the standard skills boring:
- you can have 'background proficiencies' e.g. sailor -> gain proficiency bonus in every task that has enough to do with what a sailor does (controlling ships and boats, using ropes, orienteering in wide open space, balancing on something moving, climbing poles and ropes, fishing, swimming, weather prediction...)
- you can have 'ability proficiencies' e.g. all Strength checks
- you can allow some checks only to proficient characters e.g. no Knowledge checks unless you are proficient, or only checks below a certain DC
- you can freely have checks using different combinations of ability and skill e.g. Constitution(Athletics) if the task requires endurance or Intelligence(Persuasion) if your target is particularly impressed by smart arguments
- you can create your own extended list of skills with new ideas, or split existing skills further (maybe consider handing out an extra proficiency or two per character in this case)
- you can throw away skill checks and use only passive skills
The skill system is just the default. If you change it, you have to figure out if your variant doesn't harm some characters more than others (Rogues first, Bards and Rangers second, thrive on more and better proficiencies), but besides that, you're not going to break the game if you do.
