Skill System: I see why they're making it a table decision, since it'd be hard to balance characters another way. Interesting thing to think about / discuss, though.
Skill Dice: Boo. Get rid of them (if I had my way). Do not like this over a static bonus.
Proficiencies: I don't mind there being ways to get them from backgrounds, class, race, and feats. That works for me.
Hm. If it progressed at the same rate (like, +5 over 20 levels), that . . . hm, that actually seems too weenie. Ideally nigh-epic heroes should never be challenged by things that are mundane, at least when they're trained, but having +5 from a stat and +5 from 'skill bonus' (+10 total) means you, the paragon of heroic skill-y-ness, might still fail a DC 15 check.
Imagine Batman having a 20% chance of getting spotted every time he tries to sneak up on a modestly attentive bad guy.
One, I imagine Batman has been spotted by a modestly attentive bad guy from time to time.
Two, this could be solved by having a minimum roll, based on your bonus (this has been talked about on these boards a number of times). For example, at +1, the minimum roll you can get is a 4; at +2, it's a 6; at +3, it's an 8; at +4, it's a 10; and at +5, it's a 12 (I think people usually end around minimum of 14, but I always thought that was too high).
But, that's certainly a way to deal with it, for people who want the added nuance of skills. As always, play what you like
