This is just a different way to get your personal rating up over time, not having to worry about losing a tonne of games, especially with Q times atm.
eg. 2v2
Instead of having 2 people in the arena team lose a heap of games straight, then use your 2 mains to get the rating back up, just have 2 alts lose 5 or 6 games a week, then play the next 4-5 games on your mains.
So your alts personal ratings will go down, then when u play on your mains, 4-5 wins should bump you up an average of 60 points a week.
While this isn't the quickest way to get your personal rating up, it'll go up over time, and you won't have to worry about sitting in Q's for days waiting for your rating to go down.
Can't confirm this as of yet, just started trying it this week.
And can anyone confirm, that if u have personal rating of 1850 in 2v2, and join a 3v3 team with a team rating of 1850, can u purchase the weapons?
I know there was a thread that discussed this earlier but dunno if it worked?
