I've been bringing a shiver, blitz, voltedge, and a mixmaster on my FSC runs, and I'm finding the Mixmaster single-target DPS is great for finishing off enemies after Voltedge charges.
It's lost a lot of its utility, mainly from its ability to shoot through shields and walls, but it still retains the same damage output as before.
Is there a better alternative to the Mixmaster for gunning in FSC (and an elemental gun in general?)
I use Valiance. :P Mixmaster is too slow and erratic for my liking. Another alternative is Argent Peacemaker.
