1st: Trying to play the Big Black if you can't even FC a hard map won't improve your skills at all.
And that is exactly what people trying to do compared to their skill level.
They can't even S an easy map but try to play hards, because people in the forums say they've got to play hard maps to improve, sorry but thats bullshit.
If you can't hit notes in the right time on slow and easy maps, you won't do it on hard maps, simple.
2nd: Of course there are patterns you can learn on hard maps, that won't appear on easy and normal maps but are just too fast to understand it for a new player without half time.
For example: 2 sliders close to each other with minimal timing between them OR notes directly after or before a slider, bigger jumps, fast triplets, notes of 8 and more grouped and short streams.
3rd: Yes the old maps are not timed well. And that's why they help you improve if you are comfortable with modern easy and normal maps! It forces you to read the approach circles instead of memorize.
This way you'll never get caught again by breaks and click too early in today's beatmaps.
I respect what you say and it's very true for advanced players, but i was talking about new players while advanced players improve a lot different than new players.
Of course i don't say people should play a lot of easy and normal maps if they are already good at them.
But i say they should learn the basics before advancing to harder stuff, period.
