I wanna be creative with this so bare with me. Iana and Mozzie
Mozzie and Mozzie
I main Valkyrie and Hibana,and I think they're the best,but it depends on the player
I main kaid and Zofia do I think they are really good
To be honest, every character is good in its own way, but if I have to pick one I would pick frost, her mat is great for lower rank players or on casual, because a few begginers check if there's a trap when entering a window etc. Her submachine gun does a good amount of damage too.
