Start off with low stars AND I MEAN LOW. 2* to 3* max. You wanna get used to reading AR 4/4.5 and accing it fairly decently. And then move up from there. Imo, maps with more jumps than burst are easier/more fun so you can go that route. I got good at EZ because I had sensitive eyes a while back and they would hurt if I didn't warm up with EZ first.
Honestly, it's all about keeping the motivation to play EZ that gets you good at the mod, cause there ain't no pp down this road lemme tell ya.
