I just grab a SMG after entering a server for the first time each match and see what's happening in the battle then I use:
Semis for: Sniping, Babel harassment (enemy builders), Scouting
SMGs for: Destruction, Counter-sniper action, Rushes
Shotgun: Close quarters, Tunnel clearing
Also I tend to find Shotguns more useful late game after the terrain gets changed up by all the players and SMGs are good all around. Semi's tend to be useful for getting kills on enemy forts with many defenders because we all see that tracer trail the SMG's leave off.
I do actually use the Spade as a melee weapon as it catches most people off guard (dig through blocks right into them) and the grenades are useful for clearing out enemy bunkers but they always seem to kill less people than you'd hope for.
