If you bring a Grakata, you better make sure you have loads of spare magazines as an ability....or spare Grakatas. May just be better to replace them entirely and bludgeon people with empty cheese graters.

Most firefights (assaults/meeting-engagements) are generally over within five minutes (something about that being the amount of time it generally takes for the "winning" side to sieze initiative and utter steamroll through the enemy's positions).
-If one side hasn't siezed the other's position in that time, congrats, you're both either pinned-down or too cozy as a camper in your fortified position.

Besides, the short range bullet-spammers are a close-in shock-and-awe weapon like P. Chan. Most time is actually spent jockeying for better shooting-positions w/o making yourself a suicidally easy target.

In short, full auto is something best for when you find a "fish in a barrel"/"Too many bad guys in the open to count" moment, and don't want to give them the opprotunity to find cover.
