There are many synergies or parts of synergies that seem to not effect BMGs. I was wondering if anybody has any definitive information on this:
Cannoneer [1][2]: does fire rate effect BMGs?
Nano mastery, Nano Executioner, Cannoneer [3]/[4]: no nano=no purpose. Does this bonus have a duration that can be used with another weapon?
Stalker [1][2]: Range bonus does not effect BMGs (tested using 2 of the same type of BMG, one with stalker bonus, one without). I read that the "range" bonus is actually just a modifier to the Fall Off Damage.
Quartermaster [1][2]: With .5 being the new minimum reload time, and BMGs all having .5 reload and reload weirdly anyway, do the [1] and [2] reload bonuses do anything?
Grenader [1][2], Run-n-Gun [3][4]: no recoil = no purpose
Ego Precision [1][2], Rolling Thunder [3][4], Run-n-Gun [1][2][3][4]: Accuracy?
Rolling Thunder [1][2]: Mag?
