it really just depends on your mindset. if you just think of it as practice and not as though you are playing another person then saying GG is useless.
i think that's the best i can explain it but there is more to it but really who gives a shit, just do whatever works for you.
Idra is terribly BM and often doesn't GG.
Yet he's one of the best (if not the best?) foreign Zergs in the world ^.^
He is one of the best zerg's in the world, but he isn't getting any better. The obstacle allowing him to go forward is himself.
He leaves games early, he smack talks about how op other races are, he always talks about how bad his opponent is. But with if he were to have a bit more respect for his oppositions then he would probably be so much better because then he won't take his opponents so likely.
