I believe the LN is a very separate area in which players can train, that being said, most people on osu!, including those coming from VSRGs which don't focus on LN much will start off at a rather low level, pretty much mostly inexperienced in LNs in this case.
Considering people from VSRGs which have more complicated LN patterns coming into the game also kind of sets this imbalance in skillsets, especially in the LN side, this imbalance is amplified by people throwing in LN-based converts/LN-based osu!mania maps and I think that's why there's some sort of disagreement in terms of how complicated LNs should be on the same difficulty level of rice (Almost all VSRGs base their maps on rice before LNs anyways)
Takes time for people to ease into LN maps but I highly doubt this disagreement in terms of difficulty level of LNs is going to go away :p
