As i understood nomod will help me a lot in dt, yes?
Can you play AR10?10.1 and 10.2 aren't fucking relevant at all and you'd need to strain to find a map that would give you those values between ar 8.5-8.9
Can you play AR10.1?
Can you play AR10.2?
If not you should start with those.
It's not really a waste of time, it's called doing it right as if you jump straight into something you can't do the basics of you're going to ruin yourself. We have a wide variety of maps today and they aren't all AR9 strictly. Man, it's the same as people saying "Oh just do AR10.3 240bpm as that's what the pros do" You can't just do that. Throwing yourself at a wall like that wont help in the slightest. Building up over time cementing your abilities and confidence in what you can do really helps to make you a better player overall. In the end you'll come out a lot more consistent at it.And that's entirely not my experience with having to have learned Ar 10.3 around a year ago. It didn't ruin me and I was consistently going back and playing my ar 9.6 maps for pp with 10.3 on the side at around the same difficulty level. Of course I did have already 5000+ pp even before I started touching 10.3
