I have recently bagan using NARCs on my big CW mechs to counter the ECM heavy clan decks. This Banshee is the latest iteration, just like the thunderbolts it has a perfect hardpoint for it on the shoulder. It also works very well in pug matches when you are trading midrange, put a narc in them to know when they'll peek next and greet them with a precharged gauss + laser alpha. Best case scenario you can shield with the arms until running out of gauss ammo, and then shield with the left side to keep your laser vomit. Good zombie finish with the LPL + Mlas too. I use 4 weapon groups for this: 1: Gauss 2: All lasers 3: Narc 4: The 5 high mounted medium lasers for ridgepeeking (these + NARC is a great opening to engage a new mech)
