Here's the cons for turret blowing:
Before the recent Mission update (And maybe even still. We have yet to find out.), the majority of players would recommend the Polaris and all from its branch off the Pulsar. The reason for this besides the obvious Elemental-Damage-best-vs-turrets, would be the fact that its expanded shots interrupt turrets (provided they make contact of course). With this feature, one could continually fire at a turret with powerful, expanded, Shocking shots without giving the turret the chance to return fire (and without having to use a Charge Attack like with an Alchemer type Handgun). Now however, the Silversix/Argent Peacemaker may or may not be a better choice as it was not as viable before when it fired split Piercing-Elemental Damage. Since it was not often used for turrets before because of that, testing must now be done so we can see its degree of effectiveness against turrets.
