What they need to do is make a story that makes sense for the characters. Don't hold them back, but don't push them in a way that doesn't match either.
I hate the Ric decision, but I don't hate the story of Bane ordering to shoot him. That makes sense for his purpose.
It also makes sense for Dick to hang out in Gotham for a little while to heal Bruce after he hears what happened. If he still in good terms with The Run-Offs he can ask them to fill in. They just need to include a short explanation.
What doesn't make sense is Dick delivering Zazs all the way from Gotham to Chicago by himself in Forever Evil only to end up getting kidnapped when he could just leave the transfer to the police.
About teams, Bruce tends to be overprotective and that's a reason that makes sense for him not wanting Dick in the League, even if it comes off as disrespectful or overbearing (and he is overbearing). Dick himself has more loyalty to his Titans friends, so if there's a choice, he'll stay with the Titans.
(Speaking of Bruce's overprotectiveness, this is the reason why DC or the authors' decision to keep including Damian near the League doesn't make sense to me, especially after his death and rebirth)
So I don't want them to manufacture some falling out if it can't happen reasonably.
