ME1 also ascribed a penalty to experience gained if you killed something with the Mako's cannon versus on foot. This led a lot of players to game the system by bringing things like thresher maws down to 1% health with the cannon and then jumping out to cherry-tap it to death for the full XP reward.
Not having a cannon just sidesteps that problem, in part for the Remnant Architect battles where you'd think if you had a tank cannon on the Nomad it would be ideal to do most of the fight with that versus on foot. Then it wouldn't be as much of a challenge.
Hahaha...... I did not know the penalty / Threasher Maw thing in ME1.....
Of course best thing would be to have a gun on the NOMAD and Motorized Enemies to fight, but if this is too far fetched for BioWare to consider a simple gun turret would be fine for me
