ah, to add my 5 cents to the gufire talk. 

Dire confrontation calls for dire measures, so it stands that a intermediate-high gunslinger will be as good at shooting down moving targets as an agile dodger would be at evading gunfire. Like, Grammathon cleric skilled and higher, because nobody said you could only matrix yer dodging.
Also, the equipment play a great role here: dual wielding allows for crossfire, full-auto shotguns are damn hard to avoid being hit by, and explosives are yet another feasible counter-measure. Tricksters may try using armor with hidden guns inside to take thier opponent by suprise, especialy if it's some really bulky suit, or deploy turrets as low-tier minions to be both a pain in the arse and a good distraction that allows for scoring the killing shot. 

...yeah, you probably already knew that all, but maybe not. XD
