Lol wow... And the hating continues... really? All I managed to see over the last page was a bunch of speculative facts about her fighting style which we've hardly seen so you can't even begin to fathom as to what her actual abilities are and something about Kakashi and Guy having fought stronger people than her... Is that really the best you have?
What's next? We haven't seen Hashirama or Tobirama fight... The only time we saw them was when a 70yr old man pwned them in a 3v1 fight... Are they not Kage level now as well?
I have no idea how many times this needs to be said but, just because she isn't a frontline fighter like Kakashi, Guy or Naruto - Doesn't mean she doesn't deserve the position of Hokage. What you fail to realize is that the Kage does NOT have to be the strongest person in the village... So why are you all suddenly under the assumption that they have to be?
Do you honestly think someone who has been hailed as the world's greatest kunoichi would really be that weak? Tsunade served Konoha in 2 World Wars and if I remember correctly, Jiraiya even said she was the sole reason they won a war due to Tsunade constantly countering Chiyo's poisons... He also said that no one can stand equal to Tsunade in terms of both Combat or Medical Prowess.
As for her being slow, are you joking? The first thing she taught Sakura was to be quick and evasive... Why teach someone something you can't do? It makes no sense. If Tsunade wasn't quick and evasive like she was teaching Sakura to be - She would have never survived through all her years of fighting. Go back and re-read the fight with Kabuto, she was easily able to not only dodge and evade his attacks - But she was also capable of seeing through his attack patterns and being able to turn defense into offense.
So now the only argument any of you can fathom is about that particular fight... and you know what happened in that fight? Orochimaru and Kabuto played on a fear she had, and one she quickly got over to save Naruto even though she was already in bad shape.
What you all fail to realize is if you look at the difference between Part 1 and Part 2. Those who have been given enough screen time have shown us abilities that far exceed what is possible between Part 1 and Part 2 because Kishi went from controlled abilities and power levels up to DBZ level where people have techniques that are cataclysmic. Following an obvious trend in logic, if everyone has suddenly become to powerful - Does it not make sense that, once we actually see Tsunade in battle, she's going to have also received power ups which obviously suit the theme of the Manga?
But that's right, none of you have any logical arguments.. All you can say is... "Well Kakashi can kill her with Kamui." - News flash Einstein, Kakashi can kill 99% of people with Kamui... Does that mean he instantly becomes stronger than them? No. Just because someone possesses one technique which is capable of defeating someone, it doesn't instantly mean that person becomes stronger... Why do you honestly have such a flawed way of thinking? It's so 1-dimensional and so extremely biased towards someone who is obviously an extremely powerful Kunoichi.
If Tsunade wasn't Kage level then answer this one easy question... Why is the still the Hokage? It's been like 3 years since she was appointed... Why is the still the Hokage? If Kakashi or Guy deserve it more than her, why leave her in the position if she isn't good enough for it? This question right here destroys any argument you can put together because fact is, they would have removed her from that position if she wasn't ready for the job... Better yet, they would have never considered her to begin with if they didn't think she could do it.
