How can anyone have any sort of expectation for a "The return of..." battle? These battles are always predictable. You got one guy working off the rust, and needs multiple battles to be really effective. You have the experienced guy who typically comes with underwhelming material, because they don't know how to prepare for the guy & have no idea what to expect.
Lux was the only guy that came back and did great. You then have guys like Serius Jones, Mickey Factz, & King Los who came back extremely rusty, but showed some potential.
Everyone else like Canibus, Mook & Iron from SM2, Eness vs DNA, Reed against JJDD, Cyssero against Cortez, Joe Budden against Hollow, Cassidy against Diz, Lady Luck vs O'fficial, Mistah Fab vs Arsonal, & Jae Millz vs K-shine. Who else am I missing?
These battles are always just garbage. I understand the appeal though.
The final guy I can see returning is Don q whenever he cools down.
