My mini missed Hotwire due to leveling up too fast...this is right when Fixer was released. Wonder if Hotwire can be obtained via free LT as a daily reward...or are all those commons?
They're not all commons. I suspect that you can get any common or uncommon Lt now (maybe other than the odd ones like Centurion that the game treats as Rare). http://underworld-empire.wikia.com/wiki/Categoryaily_Rewards is definitely not comprehensive, but I'm confident that everything in that category does drop as a daily reward.
