bleach ending

what'r yall thoughts on the bleach ending, i liked it but there are a few things i didnt like;
~ they didnt show us kisuke and nel's status after their fight with Nakk Le Vaar. like wtf are they dead??alive??, they lit just abandoned that plot. its so annoying
~ also where tf ichibe at, we see him doing some kinda wierd ritual after his defeat, but jeez but some light on that guy. and what about squad zero i thought ichbe could ressurect them?
~ chad being a boxer is so outta his character ( throwing hands for money)
~ and my main prob, how did the three worlds restore, like after soul kings death, i get yhwach died but that doesnt magicaly restore the linchpin holding the three worlds together...i dont get how this topic was less important than chad's boxing match which they spend the entire ep on....

anyway let me know what you think about the ending, and if u could clear some of the doubts
