Ok there is a lot of types of LN patterns to be bad at, ngl. It probably takes more focus that jumpstream to hit properly, first of all. Second of all, it requires a whole different finger independence imo, especially when doing LN-dense hybrid (just LN hybrid with as much LNs, if not more, as rice). And third of all, there simply are more ways to read them than there ever will be rice patterns, which is unironically why I like them so much more than most rice patterns - because they're a hundred times more interesting to play.
Now ofc, the only way to get good at LN is to play LN. That said, I do think at the 3* level, the main LN skillset you need to learn is the rhythmic part of LN (tho my only point of reference when writing this is a Rainy Boots ranked map and a few other 3* and low 4* I played). Usually, all LN heads need to be tapped with the same spacings in time. As well, LN tails usually tend to be released at the same time as needing to hit another note. If not, it usually is with the same timing as you are hitting them. It's not always like this since there may be the occasional 1/4 LN, which in those cases I just treat as a normal note (albeit I hesitate a bit to release my finger).
I think it's also pretty normal to be psyched out by an LN in the middle of a rice (especially stream) pattern, especially a short one or LN chord, or a normal note in an LN pattern. That's when it simply relies on familiarity.
The final goal of LN, or how I so interpret it, is this:
- Treat LN Heads like completely normal notes
- Treat LN Bodies like they do not exist (but still hold the key down)
- Read LN Tails as the space that comes after an LN ends rather than the tail itself (I do not mean use a percy skin by this, I don't lol. I mean that it's easier and more beneficial to read the empty space that comes after an LN than the LN tail)
All that said, I kinda want to see a replay of you trying to do LN, both full LN and LN Hybrid, or just simply know in what situation you miss or get terrible accuracy on LN. It's one of those things where a lot of bad habits can exist that are hard to notice. In fact, there was this really old forum I just kinda projected my previous LN struggles on (
community/forums/topics/1992743?n=1) where I just list the ways I miss on LN so much and still tend to do, but noticeably less than before. (Edit: do not revive that forum lol, I am simply referencing it)
