well good luck...there are to many minato haters out there, that clearly underestimate him. While he has not shown any really destructive abilities, he also being a master of fuuinjutsu, has shown few seals. And where did he learn that from. The uzumaki. And which clans were destroyed for being powerful. Lets see...: kinimarus clan, hakus clan, the uzumakis, the uchiha, senju?(i think senju clan split, into konohas clan, but it is possible that they were destroyed as welll).
So simply put, while minato is more skilled than many people think, he is not all powerful, as there are skilled people who can counter minato. The best opinion of minato, is that he is very powerful, likely in the top 3 of the hokages, but not much is known about his skills and abilities. Keep in mind, that minato was very young, likely still in his 20s(probably later 20s) and he still had more techniques to learn. and he has one great feat, that demonstrates his power. He made tobi look like a fodder. And tobi hasnt shown much improved personal abilities since then, other than using gedo, and controlling the paths.
My only purpose here is to talk from a more neutral perspective. While there are many people who overrate minato, there are many more that underrate him. The point made by the maker of this thread was valid, that minato has many ways to take out enemies. The only thing he did that was wrong was try to make it seem like minato was able to take out any person. As with all absolute defences and absolute attacks, all of them are counterable.
