this is a solution for ppl who don't have a team, or are in a team where nobody is online on.
What to do if you don't have a team?
if you don't have a team make a random one you can leave it afterwards.
So here's what you do if you're in a team:
pick 'join teamlobby', it'll say there's no teamlobby at that moment and asks if you want to create one. Pick YES!
If you're in the lobby, search for custom ranked team match and pick OTL.
If you're either lucky/good you might come across a 2man team that you can beat.
I had a target score to aqcuire of 5000 and a 2man team will have a target score of 7500. I did an imediate combo of 5,675 and landed it asap. Got me a 1-0 for me, after that i needed to grind some glass wall with a 500 point grind. I landed it first with a score of 1,721 and got the 2-0. After that they came back with the gap to 2-1 but wasn't enough.
So i won and the achi was mine.
Hope it helps those who need it :)
