I also dislike the very unrealistic "Switch Character" option, so I'm starting to think that maybe my solution here is to have a smarter (INT 14) character, and just try to learn the important skills myself.
Sure, CC'ing Computers and Repair will result in a kinda low score anyway, but it's cooler with my Scoundrel/Guardian to do it all himself.
I'm thinking of doing this:
Scoundrel:
STR 14
DEX 14
CON 10
INT 14
WIS 14
CHA 12
I know my Persuade suffers, but since I'll be maxing it, it'll be higher than any non-Scoundrel anyway. As a Guardian, I know lowering CHA from 14 to 12 hurts FP as well, but I would have had the lowest in my party anyway. Since I plan on concentrating on only 2 NPCs anyway, this allows more force powers since I will have 2 Jedi NPCs instead of 1 and 1 skilled NPC.
I'm thinking about using Bastila and Jolee, although I'd consider using Juhani instead of Bastila.
