Is hard when your are seeing your main character that is going to die, all we can do is accept it and let it go, then make a bunch of tributes in the name of that character, it was hard to see jiraya die but it was the best thing that happen to the manga because i woulnd have the impact that it did.
Itachi died like a true hero, even when he got a tribute years ago after his dead he got resurrected and died again like a true hero and got the respect deserved. and the fans had to deal with it. because that dint made the character less important than what it was, instead made them better.
even minato, a dude as powerfull as he was, sacrified for the wellbeing of his village, it was hard for his blizters to let it go even when they knew he has being dead since the begining of the serie. but still a hero.
Do you want your favorite died like a True Hero or life like kid hero?
Time for tsunade to shine and sacrificing the half dead life she has now to revive the kages have her tribute and died like a slug, kishimoto made tsunade shine by killing a tsusano clone (fans happy) so time to keep going.. or are you expecting more from a sexism like kishimoto? because that is really naive.
I agreed with one thing, if obito >_> survived then that is a piece of cake for tsunade to life, the moral heart of the story will be noone ever dies in a war.
now tsunade's fan are taking things to extremly like if the world or the manga was going to end because of the dead of a character like tsunade, i like her i really do but the sad and true reality is that she is not minato,itachi or jiraya if the manga din't went down when they died it wont because of tsunade. so accept it and move on

but since kishi is kishi xD tsunade will life and be a hero like naruto.
which is the worst case of being a hero that can happen to her.
Now how madara wooped the kages, well he might have gone tired of playing game with them and decided to go for real or made 100 clones like only naruto can do and overrun them, probably taijustu battle. but that is kishimoto. that is the same as Harishama>madara
noone knew how it happens, even when the evidents and feat Harishama<madara. not even kishimoto knows how that battle went he is really overthinking how he will pull that shit out of his ass and make it believeble.
plot need to progress so death>tsunade ''Deal with it''
