Yeah, I've always run a discrepancy between 'normal' folks and 'runners/high grade folks. Your average 'professional' has an 8 die pool before modifiers; 4-5 from Skill, 3-4 from Attribute. Average office workers have 5 Computers, 3 Logic, with the occasional smart-dude running 4/4 or maybe 4/5. Average cop has 3 Intuition, 5 Perception, average boxer has Agility, 4 Unarmed Combat, etc. Some of the metahumans can throw this off a little; your average ork or troll has a higher dice pool for manual labor, sure. An elf is better for Customer Service.
Your experts have dice pools around 12, your dabblers have 4, your perfectionists have 16+. I use the tiers (based off of the dice pool, including 'ware/magic but not equipment) for buying hits as my rankings.
