This really only applies to Classic Traveller and is addressed by both basic training and background and connection skill packages in MGT2
So every Scout has at least Pilot-0 and every party should have at least one Pilot-1 or whatever however they roll.
And your average 4 term MGT character should have 2-5 background skills at-0, at least six basic training skills at-0, a minimum of 3 1+ skills and probably 1 to as many as 6 more depending on advancement and event rolls plus 2 connection skills and one or two background package skills.
Something I'm experimenting with now is rolling up characters who roll every term once each on all the skill tables they are eligible for but having all skills earned from the table start at 0 rather than 1 and dispensing with extra background and connection skills.
This seems to produce much more rounded and plausible characters who can do everything you'd expect someone from that career to be able to do but will by looks of it need balancing out by being tougher on difficulty levels or maybe applying bane dice a lot more.
Another alternative is to let them roll once per term as usual but let them choose the table after the roll - or just plain choose your term skills without any point-counting required.
