How would you build a weapon that's autofire capabilities scaled with the users SPD?
For example, a MP5 has an average ROF of about 800 rounds per minute. This would mean a maximum of 200 shots fired in one full turn (17-18 shots per second). So a character with a SPD of 4 would need autofire 50 in order to be able to fire 200 rounds per turn, but a character with a SPD of 5 would need autofire 40. Regardless that the fact that the autofire would be absolutely ludicrous, what would the AP cost of such a weapon be and how would it be built?
On that topic of ridiculous autofire numbers, how would you build an extremely high rate of fire weapon? It seems as though any weapon with an autofire above 5 just seems almost useless, as you'll more than likely never roll high enough to hit with any more shots than that. After a certain amount of round per second, would you then just up the damage, or give it other bonuses such as AOE one hex or PSL's for overcoming the penalties for autofire and suppressive fire?
By comparison, an autofire 5 weapon in HERO only has a ROF of 80 with a SPD 4 character (which is chump in today's technology for automatic weaponry), not to mention what the ROF capabilities would be in the future!!?
How would you approach this situation?
p.s. - a minigun would need an autofire of insanity to accommodate the 100 rounds per second the top of the line ones the military has.
