Having a main allowed me to get better at brawl as a whole (believe it or not >_>) When I picked D3 and stuck with him I started to learn more about how he worked in comparison to other characters in all sorts of ways. Granted I can play most characters decently (exceptions being Sonic, Falco, IC, and Olimar) I play D3 (and my second, Marth) at my best and they really compliment each other. Focusing on only a couple characters leaves you open to their weaknesses, but as a player its up to you to decide whether you want to find a way around those weaknesses or just add another character to make up for them.
