As said - not an option. This WILL be the character generation used. No one in the group is willing to use "dictatorship of plastic lumps" in CharGen and none has been in decades (Rule systems that force that won't get looked at)
That's unfortunate in some ways, but understandable. Every group will have its preferences. The thing that's great about Traveller random chargen is that it produces the best characters for the mechanics of the game. Overly optimized characters can break the 2D6 mechanics with their enormous die rolling results.
"Hey, Bill, make a sensors check."
"Okay, I have Electronics (sensors) 3, a +1 for my INT, and another +1 for my Expert software. Boom! I rolled a 13 and I only needed an 8!"
[Note: Getting a level 3 skill with a rando is tough but easy with point buy if given the points]
I'm not saying that player characters
shouldn't have high skill levels, but a team of optimized characters produces a whole lot more over-success on skill checks. Failures and retries make for fun sessions, too. YMMV
Traveller, at its heart, is also designed to tell the tale of "ordinary people" doing exceptional things. Randoms kind of makes that happen. Optimized point-buy characters might still accomplish that, but it takes the element of chance out of it. Just my $0.02.
