I like the Widow but it's surprisingly under-powered. It's great on bronze, good enough on silver, but less then good on Gold. And don't try and take it to a fight with an Atlas, or any boss-level enemy. Unless you're good at getting headshots. In that case, go for it.Got a Batarian Soldier and a Krogan soldier in Spectre packs, as well as the Asari Justicar and the Geth Engineer. The Engineer isn't as good as I'd expected it to be, honestly.
