My girlfriend finally hit immortal 1 and wants to stop playing ranked for the rest of the act. I was wondering with just 1 win in immortal does she get the buddy?

so i play as sage and dont get a kill because they surrender and my team trashes me in unrated lmao. people treat unrated like comp how the fuck are people to get better. like obviously by playing unrated

i go ghost and one ability and my friend js goes straight up sheriff. and another example is like classic and light shields or short and an ability. but what is a good buy during pistol rounds in ur opion?
