Im a 80k rank osu mania player that has good speed but lack stamina and acc in long maps (<5mins). I also struggle with dense streams and alternating patterns in the 3* range. I recently started to S rank some higher 2* maps after a month break, even to the point of surpassing my best by 100k in some maps. What should I primarily focus on according to my rank and what are some good beatmaps for stamina?
