I got mine on my first hard mode run which was two weeks ago, I fully lvled it up and I use It When I think using a shotgun will get me killed and when a sniper will sometimes have trouble hitting targets (my aim is not the best) so I use it pretty much all the time especially at medium rage wizards an tons of thrall a but I usually would switch to my thunderlord when fighting thralls so I can generate tons if orbs on my defender titan for my teammates. But yeah I use pretorian foil quite often but for me the accelerated coils is a must.
