I've been grinding the 50 wins too and it's been pretty rough.
Had a few matches today where we were put up against full teams with the 100 streak badges. Pred, 100 streak, 20 bomb, and between 5 and 10,000 kills in arenas each. Like Jeez.
Meanwhile, on my end it's like the guy on our team has literally just dropped out of the tutorial. Quite literally sometimes we get a level 1 lifeline. One of them yesterday hit 14 damage across SEVEN rounds.
Still, it's not hard to get the wins... it's just annoying mostly. I don't really love arenas, and the matchmaking is so messed up that it makes it hard to get good matches much of the time.
Genuinely believe that the game feeds you level 4s and that when duo queueing for arenas. It's really really bizarre. Triple stacking it is alright, but then you are usually facing great players which I suppose is fair, but it isn't exactly fun when they have those kinds of badges and kills for arenas lol. It justs becomes a poking match to see who runs outta meds.
