Yea. Tsunade keeps the fighting force alive. It's pretty useless to be a leader of a village that can only depend on its Kage when a threat arises. Tsunade gives the ninja a chance to fight another day if they don't die on the battlefield.

For one thing, her summon owns Manda, if only for the fact that it can't be killed with any sort of practicality (or maybe all it would take is someone pouring salt ). "Own" meaning "won't be beaten but probably can't attack for squat, either" .
Seriously, though, Tsunade's medical jutsu are unmatched, and she takes time to teach anyone, and uses her own time to heal her troops. It's sort of implied, but I'm of the belief that sometime later, it's going to be revealed that partly because of her legacy, Konoha has the best medical corps out there.
The only reason Tsunade "sucks" is because her usefulness as a Hokage aren't the stereotypical Hokage traits: battlefield leader and impressive array of offensive jutsu.
My last and most important point: Tsunade is the only Hokage we know as a real person. We know her bad habits, her stupid moments, her moments of hesitation. Every other Hokage has been pictured as a "flawless leader" simply because Kishi has not had enough time to show them develop. On the other hand, we have only had time to see Tsunade's failures as a medical ninja and not her accomplishments. Comparing a "bratty princess turned leader" to a "flawless leader" will surely make one think that Tsunade is not up to par, but I believe sooner or later, it would be proven otherwise in the manga.
Tsunades most important and powerful traits are as follows:
1. Her medical knowledge makes her aware of ways to mess with the natural function of the body. We saw her do this to Kabuto in the Sanin fight. Kabuto is a genius at medical jutsu as well which is what allowed him to get out of it, but id say that other shinobi would be in trouble if she landed this on them...
2. The Taijutsu- That insane strength can do some serious damage to someone if it hit them...This was why Orochimaru and Kabuto ran when she was trying to punch them at first because she had her full strength at that point and if a punch were to hit them they would be screwed...bad.
3. The Genesis Seal- The Ability to heal battle any wounds..The limit to the genesis seal is how much chakra she is able to accumulate and we are unaware of exactly how much she can accumulate. Sure it has the limitation of it taking away her living years but add this together with the rest of her arsenal it makes for a rather formidable opponent..
4.Senju blood? - We still dont know what if any advantages this brings but this surely has a drawback...Madara will surely want to take revenge on her for being Hashiramas granddaughter..
5.We havent seen her fight since she got over her phobia of blood. This is important also since this paralyzed her during the Sanin fight..
I can give tsunade credit because she was the only one mature enough to want to change

You would be wise not to underestimate Tsunade she carries the title of Sannin for reason. There are many factors for being Hokage like having sound judgement and wisdom are important because Hokage is like a president they do alot of adminastration work.
Tsuande is stronger and alot more skilled than you think. In the trio Jiriaya was the clumsiest, Tsunade was the sharp one. When she gets serious you will see whats she's capable of.
Dont forget if it was not for Tsunade, Neji & Choji would have died & Lee would never be a shinobi again.
What chakra type are you?
She is not.
After Jiraiya passed away (may he RIP), she became the most powerful shinobi in Konoha.
She is also very intelligent. Not only can she handle the most impossible tasks when it comes to medical-stuff (thinking about Lee), but she is also smart when it comes to combat (when, during the wars, she told the Hokage that there should be one medical ninja in every team).
Trust me. Kishi will show us why Tsunade was one of the Sannin.
Awesome, just awesome
