http://osu.ppy.sh/s/53834To map the easiest diff I always try to make long sliders. Most of them curved with good shapes. Sometimes, to give the diff some variaton I make some long slider with a weird but symmetrical shape.
About rhythm, I NEVER place notes at red/blue ticks cause they're way too difficult for beginners to click or understand when to click them. They're just too much :l
I use more sliders than circles. For example, a long slider of 3 white ticks, and after that another long slider with the same duration as the previous one. In special cases I add a circle between 2 sliders (if it is really needed. this depends on the song).
When placing notes, I always try to place them in a clean way. WIth this, I'm reffering to placing notes in a way that they don't get overlapped with other notes or by their respective hitbursts. This is to make it more easier for beginners to read the notes and patterns.
I like to use the bigger circle size. I find it more easier and suitable for the easiest diff. About approach rate, I always check if the AR makes the patterns a mess or more easier to read so I try to set it low, but not too much to avoid that. Eeeh about slider velocity, I always set it at 0,80 or 0,90 (it depends very much on the song. if the song has very high BPM I might set it a bit higher, like.. 1,00 or 0,90 to make the diff feel better when it is played).
I hope it is enough. o.o
