Yes, but Tsunade's roll along this time has been more of a Hokage (for the people) and less of that of a fighter. She's saved countless lives.We were just introduced to mei, we know tsunade for a long time. Most jinchuriki are pathetic, if they weren't, they wouldn't get owned and their tailed beast wouldn't have been consumed by Tobi's statue thing.
Gaara is not pathetic.
Naruto is not pathetic.
Killer Bee is not pathetic.
The three tails got double teamed by Deidara and Tobi, most of the characters we know can't survive that. Not pathetic.
The four tails went against Kisame, I guess this wasn't that bad, but still Kisame is extremely powerful. Still not pathetic. Killer Bee and Guy had trouble with him, they are not pathetic.
It is unknown how the five tails was captured, so we can't say.
Six tails was captured by Nagato, not pathetic, Nagato is top 3 Akatsuki.
It is unknown how the seven tails was captured so we cannot say.
For your sake, I'll give you the 5 tails and 7 tails so your argument that "most" Jinchuurikis are pathetic doesn't humiliate you that much, other than these (which are debatable) the others are certainly not pathetic.
I'm starting to think you don't know what pathetic means..
