[Research Labs Aren't A Garbage Bin, De]

Have you actually tried to fire two weapons at once?  It's not plausible as seen on TV and in the movies.  There have been a few examples in history where the odd gunfighter in the old west and maybe modern trick show artists are able to do it, but those are special and talented people, that probably trained extensively.  It's not as easy as putting a gun in each hand and hitting the target, especially at range with both weapons.  The AK Link theme seen in the dual pistols fits with the super soldier space ninja theme of the augmented Tenno.  It would take scientists' research to have integrated systems allowing for the effective use of guns akimbo either cybernetically through the Warframe suits or bioengineering in the operators to make this talent ubiquitous.

 

Got nothing for your other arguments, though.  I think I'd like to see research weapons be a little more unique as well rather than just stylized counterparts with some minor stat tweaks.  That Mutalist Quanta is thinking a little outside the norm of this game's usual weapons but I find myself not partial to using it.  But, at least its a step in a different direction.  Would be neat to see AK weapons hitting two different targets at once with some alternate fire mode or something like a pistol stance of sorts.
