Hello, This thread has turned into more of a rant and less of a suggestion, so it will need to be closed soon, but before it is closed, I'd like to clarify/gather some information to submit to the devs first.

1) What would you like to see nerfed about the ninjas in question?
2) What ninjas would you like to see replace them as the top ninjas of the current meta?

So far from the current posts I'm seeing that you would like to see Kushina's scaling reduced.
You'd like to see Gaara's scaling reduced, and to counter this, you'd like to see him given offensive abilities on par with Jinchuriki Bee, who you used as a comparison point.
You would like to see Minato's dodge chance reduced (perhaps to a flat chance rather than being based on combo? I assume your combo is low based upon your post?)
You would like to see EGF Kakuzu nerfed, specifically reducing his heal and damage output?
You would like to see Tsunade Reserve Seal nerfed, causing her to give the allied teams a debuff that makes them less likely to dodge?
You would like to see Summer Kurenai nerfed, but I need clarification on how.
You would like to see Ibiki nerfed, but I need clarification on how.
You would like to see Summer Kakashi nerfed, but I need clarification on how. Thanks!

Alright, this thread has turned from suggestion thread to a discussion thread, so I do need everyone to take it to a different forum if you want to continue the conversation. Unfortunately, threads in this forum are meant to be brief and solely for the purpose of reporting bugs and suggestions, not for long-winded discussions, but please feel free to continue this discussion elsewhere. I will take all the suggestions into account when making my report for this thread. Thanks!
