Okay, finally managed to read through all that. Unfortunately, I agree with you in almost everything. There was too much wasted potential and unused opportunities during Volume 4.

In particular, I was looking forward much more to Taiyang meeting Raven (since they actually share history together and whose interactions with each other could bring out sides of themselves that they don't usually show) rather than Yang meeting Raven. I was very dissapointed when it became evident Tai wasn't going with Yang, for a reason that we weren't told until the last possible moment (even though earlier it was implied that Yang was the reason he wasn't going).

My problem with Ren's arc is that it was dissapointing, simple as that. And I'm not talking just about the fight. Even if it overtook the other arcs, more could have been done with it.
