Do I think so ?
Hells yes.
To write really complex schemes you have to
have a hold on the English language.
Listen to dudes like Elzhi or Crooked I.
They often use multiple definitions for words.
Inner rhyme, end rhyme, beginning rhyme, metaphor
etc.
To say some really crazy shyt all while flowing on beat
and injecting emotion.
Royce is really good at that especially when he does his Pac
impersonation.
Using multiple definitions, metaphor and the like allows them to go beyond just
rhyme schemes, you can rhyme words forever but eventually you'll stop being
coherent thus the need to use metaphor, simile or a punchline to keep your point.
Sh1t gets even harder when you're telling a story or sticking to a
theme/topic.
