If I would have know Boone & ED-E were in the game an are psychos that destroy everything I would have not invested so much into combat skills ^_^
that doesn't excuse your screwed up character build, however
developing one or two combat skills is more than enough(thus leaving you ample points to put in elsewhere), and complaining about not being able passing late game speech checks when it was your decision to ignore this skill seems a bit off.
you've chosen to rely on force as the only problem solving method, now it's time to live with the consequences

though, i'll never understand how anyone could ignore communication skills in a game that has so much dialogue
