They should've listened to RZA more, but egos got in the way and everyone thought they didn't need RZA anymore. RZA 93-97 is arguably the GOAT producer, but he shouldn't stayed truer to his sound instead of trying to be too digital.
Hindsight is 20/20, but even after Forever, they could've just made grimy 1995 sounding ish forever. With the exception of Ghost who sounds ill on the marvelous SC style beats, or Meth who's extremely versatile, they sound their best over the gritty 36 Chambers/early solo style beats. But it's hard to tell artists to keep doing the same shyt over and over, especially with hip hop rapidly changing year by year in the 90s.
