As for why I wanted CJ off the team, I kinda wanted him to just sort of retire from the gang world, since he lost his mom(and the grove street gang), I felt he was kinda traumatized, so in my eyes Team Wheatley was to be a fresh start for him, but ended up being worse as some of the members were GENUINELY RETARDED, and Order 66 REALLY f**ked with his head, so he actually considered leaving, but he didn't want to join another team, instead sort of retire. Though the Damage from Order 66 was intense, once the new patch came in(eg the rebirth of the TMCU), he decided "eh f**k it" and participated in the Battle for Monty, and when he saw Wheatley NOT using a good strategy or same moves, he was like "okay f**k this shit I'm out" and left.
wall of text I know, basically he left because wheatley's tactics were...sorely lacking
