Four pages of discussion is not a gauge for the effectiveness of the argument. I also don't think what's happening here is systemic abuse in any quantity. Multiple people have all agreed that guns outside of high tier fights are intrinsically unfair against any character not totally prepared/outfitted for them, save you are severely nerfing bullet-speed for the sake of fairness, which I admittedly dont see many people do.

This is also not an attack but an outside observation. I have fought gunslingers and spell-guns aplenty and I personally have no real qualm with it provided my every post blocking/evading is not nitpicked to cheese a win because 'but bullet Su fast! Yew can't dodge!' That has happened more times than I care to count, not that it effected the outcome.

I think Dark and Nobody made very good points for their case, however. There were very few actual-scenario defenses provided by the gun slinging side to empower their argument that weren't entirely hinged on characters being prepared beforehand or some kind of deal being struck, or other circumstantial/convenient factor. 

Just my two cents.
