Zzzzz Another Tsunade anti-fanboy..
Look at the facts not your opinion. Oro fight:
AFTER she got over her many years-long fear of blood, and took a ton of straight on attacks from kabuto, and 2 mortal strikes from Oro, she healed herself to full in a matter of seconds, stopped Oro, Kabuto, and Manda(the most powerful summon of all who outmaneuvered Jiraiya and Gamabunta and was feared by many -) with a gigantic 6 story sword she threw around like a Kumai pinning the quick Manda. She defeated them all and was still standing with enough energy to keep on fighting when they finally were forced to flee.
Now lets look at the Pein arc. She was able to heal thousands possibly tens of thousands of villages after she summoned her Slug. And as it is stated many times healing takes a ton of chakra. She not only HEALED thousands, but shared her Chakra with those on the battlefield through her slug. THEN she was ready to fight Pein when she confronted him.
Those have been really the only two fights we have seen any neither of them we have seen her take her fighting limits to the max - so why all the random hate threads? In all honesty she did much more than most kages during the Pein arc who would have fought and died - she saved many lives and then STILL was ready to fight and die to hold him off until the backup arrived.
Silly opinionated thread.
