Considering that Jiraia, Nagato's mentor and a Sanin could not stop Nagato, it's clear that Tsunade walking in and fighting him would've been pointless. She went to heal people in order for their long-term strategy to work: Figuring out the secret of pain that could defeat him. Naruto could only beat Pain because he had knowledge that Jiraiya lacked: How many there were and how this technique worked among other things. Tsunade's strategy worked. I don't see the problem.

Hashirama is a ninja in his very own category so comparing to him is pointless. The Third would've had his ass kicked as the Older ninja. His Reaper Death Seal is useless against the Six Paths of Pain. His abilities would not match up against Pain. Even in his prime he would not be able to defeat Pain because of the Preta Path: chakra absorbtion. Sage mode is essential to beating Pain.

So no, i think that Tsunade did fine during Pain's assault. In hindsight some things could've been done better (Not sending Jiraiya and having him on standby would've bought them a lot of time and saved many lives) but that's hindsight.

If every Kage that lost a battle, isn't fit to be kage, there wouldn't be enough space on the mountain for the hundreds of Kage needed to fulfill that condition.
