I've only really played standard osu seriously and im thinking about giving mania a try since it seems really fun c: Anyway, do i need to be able to play 4k, 5k, 6k and 7k (im guessing those are the main ones?) well to play it at the top level. Or are there top players that for example, only play 4k?
The main modes are definitely 4K and 7K. If you play 7K, well at least for me, I tend to get a lot of skill and ability in other keymodes (5K 6K 8K) too.
It's all about what you find fun really, but I definitely do recommend learning both. As laishiou said, a very large majority of the mapsets here are 4K and 7K, so you only really 'need' to play them in order to get a higher rank, at least.
Yes there's higher rank 4K players that only really play 4K, but maximum their rank tends to cap out at around #300~1000, since there isn't enough harder 4K maps ranked currently. But osu!mania is still a growing game mode, and things will change quite frequently, compared to standard at least.
Just play what you enjoy, but note the popular keymodes are 4K and 7K. I highly recommend you get a feel for both of them.
