Soldato
Finally had a great game with two randoms for my last match of the night. Everyone was pinging things, dropping loot which other people needed etc. Two of us ended up with the Mastiff and the other had digital threat optics on both weapons. The last enemy squad was holed up in a building. Popped my smoke and instantly the Blood Hound pinged the enemies, ult'ed and we burst in from two sides. Fight lasted about 3 seconds...Victory! Sometimes it all clicks and comes together without a word being said.
I find this with randoms... particularly the "all comes together without a word being said" then on the winning screen everyone comes alive with cheering and gg's on the mic
