I did it with Alex / Guile. Mostly Guile nowadays. I would have to say I get pretty lucky on matchmaking and Id run into 9k / 10k opponents around 10pm-1am PST..the thing that was cool was id run into the SAME dude like 6x in a row! Id milk those BP like a hungry baby sucking on a fat titty. I went from like 6400 to 7600 in a matter of 3 hrs.

here are some tips if you wanna grind it out

1. Before going ranked, play with a good buddy who is higher ranked than you for about an hr; it gets the juicex going and when you get in ranked, you're a bit warmed up

2. Use Discord, there are alot of SFV chatrooms with some beasts always grinding; I learned alot in those sessions

3. Shimmy / frametrap / be sneaky. This game is not meant to be played clean..it's probably the most dirtiest and mashiest version of SF to ever exist.
