Generally speaking, though, it sounds like a significant portion of the group - Sherlock, myself, wander, Kunoichi, ReZL - already has a solid grasp of what it takes to make a character, or has a character already made (in wander's case). The whole idea of the Package creation is to make a character equal to your typical EP starter. If the people who aren't familiar with making an EP character want to, they certainly can use the Package system, but I know at least for myself, I would prefer the flexibility of a standard creation setup.
The reason people don't feel like they're good at a skill unless they boost themselves up to the cap is quite simple - while it may be true that, for example, Kinetic Weapons 40 is equal to army rifle certification (not a simple task), it doesn't necessarily feel that way. With a 40, you're going to fail 3 times out of 5 when you're asked to roll. A common reply to I hear to that is 'well, just buy up Moxie, it lets you flip dice rolls.' The problem there is that buying Moxie, while good, isn't quite the boon some make it out as. Yes, with Moxie you can flip dice rolls. But unless you're using the Motivational Moxie option from TH, or your GM has some houserule that lets you gain back Moxie, you get to use it a grand total of once per number. 4? You get to use it 4 times. In a span of maybe 4-8 hours? And when the bullets are flying, so are the dice - and unless you have Moxie 10, you're probably not going to be spending Moxie every time.
Plus, Moxie is expensive - 15CP per point. Invest that same 15CP in a skill, let's say the one starting at 40? You have increased your chance to-hit from 2/5 to a little over 1/2. That's a lot better odds.
Also, worth pointing out. Firewall doesn't just recruit anyone. They want the best, they want badasses as part of their org. Why? Because your average transhuman can't take what Sentinels are supposed to.
